Sangoma Connect Mobile

Revolutionise Your Business Communications: In the modern corporate landscape, the traditional office desk is no longer the sole hub of productivity. Whether your team is working from home, travelling for client meetings, or managing critical on,call shifts, the need for seamless connectivity is paramount. Enter Sangoma Connect, the mobile softphone application designed to turn your smartphone into a fully featured business extension.

For businesses looking to simplify workforce management and reduce the complexities of on,call rotations, Sangoma Connect offers a robust, secure, and cost,effective solution. This guide explores the extensive feature set of the application and demonstrates how it can transform your operational efficiency and bottom line.

What is Sangoma Connect?

Sangoma Connect is a high,performance mobile application for iOS and Android that integrates natively with Sangoma PBXact and FreePBX phone systems. It is engineered to provide a consistent “in,office” experience regardless of a user’s physical location. By leveraging VoIP (Voice over Internet Protocol) technology, the app allows staff to make and receive high,quality voice and video calls using their business phone number, ensuring professional identity remains intact while keeping personal mobile numbers private.

The application is more than just a dialler, it is a unified communications (UC) hub. It bridges the gap between traditional telephony and modern collaboration tools, offering everything from instant messaging to multi,party video conferencing within a single, intuitive interface.

The core of Sangoma Connect is its ability to deliver crystal,clear audio and high,definition video calls. Because the app uses the business’s PBX infrastructure, calls are routed via the internet (Wi,Fi or mobile data), providing a reliable connection even when cellular signals are weak. This is particularly vital for on,call staff who must remain reachable in various environments.

Gone are the days of manual configuration and complex setup codes. Sangoma Connect features a “magic link” onboarding process. Once an administrator enables a user in the PBX management module, the employee receives an auto,generated email. By clicking the link within the email, the app automatically configures itself, logging the user in without the need for hostnames or passwords.

Understanding the availability of your team is crucial for efficient workforce management. The Presence feature allows users to set their status, such as “Available”, “Away”, or “Do Not Disturb”. This status is synchronised across the entire Sangoma ecosystem, including desk phones and desktop clients. For managers, this provides an at,a,glance view of who is ready to take a call, which is essential for coordinating on,call responses.

Managing messages is simplified through the Visual Voicemail interface. Instead of dialling into a system and listening to prompts, users can see a list of their voicemails, see who called, and play back messages in any order. This allows on,call staff to prioritise urgent queries quickly without wasting time on administrative navigation.

Professionalism is maintained through powerful call control features. Users can perform “blind” transfers (sending a call directly to another extension) or “warm” transfers (speaking to the colleague before passing the call over). This ensures that customers are always directed to the right expert with the necessary context.

Collaboration often requires more than two people. Sangoma Connect supports native 3,way audio conferencing, allowing users to add a third party to an active call instantly. For larger groups, the app integrates with Sangoma Meet, providing a platform for multi,party video collaboration and screen sharing directly from the mobile device.

Security is a non,negotiable for modern businesses. Sangoma Connect uses advanced encryption protocols, specifically TLS (Transport Layer Security) and SRTP (Secure Real,time Transport Protocol). This ensures that every conversation is private and protected from eavesdropping, whether the user is on a private home network or a public Wi,Fi hotspot.

Push Notifications

To preserve battery life without missing important calls, the app utilises push notifications. The application does not need to run in the foreground to receive an alert, the system “wakes” the app when a call or message arrives, ensuring reliability for on,call personnel who cannot afford to miss a notification.

Strategic Advantages for On,Call Workforce Management

Managing a workforce that is frequently on the move or “on,call” presents unique logistical challenges. Sangoma Connect is specifically tailored to address these pain points, creating a more agile and responsive team.

Simplifying the On,Call Rotation

When an employee is on,call, they are often tethered to a physical handset or forced to give out their personal mobile number. Sangoma Connect removes these barriers. Because the app acts as a secondary extension, managers can use the PBX’s “Follow Me” and “Call Forwarding” features to route calls to the on,call staff’s mobile device automatically.

If an on,call technician is busy, the “Presence” indicator lets the rest of the team know immediately, allowing the system to route the call to the next available person in the queue. This level of transparency reduces “phone tag” and ensures that urgent client issues are resolved faster.

Professionalism and Privacy

One of the greatest benefits for staff is the separation of business and personal life. When making an outgoing call via Sangoma Connect, the recipient sees the company’s caller ID, not the employee’s personal mobile number. This maintains a professional image and protects the privacy of your staff, which is a significant factor in employee satisfaction and retention for those working outside traditional hours.

Increasing Productivity Through Unified Communications

Productivity is often lost in the “spaces between” tasks, the time spent checking various apps, returning to the office to check a desk phone, or trying to track down a colleague. Sangoma Connect recaptures this time.

Real,Time Collaboration

With integrated team chat and file sharing, employees can collaborate on the fly. An on,call engineer at a client site can instantly message a senior architect for advice, send a photo of a technical issue, or even start a video call to show the problem in real,time. This immediate access to collective knowledge drastically reduces the “Time to Resolution” for complex tasks.

Geographic Flexibility

Sangoma Connect empowers businesses to hire the best talent regardless of location. Because the communication system is entirely portable, a business based in London can have on,call support staff in Manchester or Edinburgh, all appearing as if they are sitting in the same office. This flexibility allows for better coverage across different time zones without the need for expensive regional offices.

Unlocking Cost Savings

While the productivity gains are significant, the financial benefits of adopting Sangoma Connect are equally compelling for any business owner or IT manager.

Elimination of Hardware Costs

Traditional business telephony requires a desk phone for every employee. With Sangoma Connect, your employees’ existing smartphones become their primary or secondary business devices. For remote or mobile workers, this eliminates the need to purchase, ship, and maintain physical hardware, leading to substantial savings on capital expenditure (CAPEX).

Reduced Mobile Tariffs and Roaming Charges

Since Sangoma Connect uses the data network to route calls, it bypasses traditional mobile voice minutes. For businesses with international on,call requirements, this is a game,changer. Employees can make “internal” calls to the office or other colleagues for free from anywhere in the world, provided they have an internet connection, effectively eliminating expensive roaming charges.

Simplified IT Infrastructure

Sangoma Connect is managed via the same interface as your main phone system. This centralisation reduces the administrative burden on your IT department. With automated provisioning and cloud,based certificate management, the time required to manage mobile extensions is reduced from hours to minutes, allowing your IT team to focus on higher,value projects.

In Conclusion: Sangoma Connect is more than an app, it is a strategic tool that empowers your business to be more responsive, more professional, and more efficient. By simplifying the management of on,call staff and unifying your communication channels, you create an environment where productivity thrives and costs are kept firmly under control.

Whether you are a small business looking to scale or a large enterprise seeking to modernise your workforce management, Sangoma Connect provides the features and flexibility required for success in a mobile,first world.

Gradwell IP Address ranges

At Gradwell, they send internet traffic from different addresses (known as IP addresses) to allow their telephony systems to work smoothly. Below is the list of IP addresses where their VoIP (Voice over IP) traffic will come from. It’s important that your firewall allows traffic from these addresses however they recommend you don’t set it to allow only from these, just that they are included.

The reason they say don’t allow only these addresses is that there network is dynamic and may shift or new items added and we don’t want this to affect your service.

There are a couple of things you should do to ensure you get the most from the Gradwell Voice services:

  • Check your firewall filtering – is there anything being excluded?
    • If yes – Allow the IP range traffic – this will most likely be in your firewall settings or tools (they all differ so they can’t exactly point you there)
    • If no – you’re good to go
  • If you use UDP traffic then you’ll need to allow Media ports (known as RTP) with the numbers 1024 to 65535

Disabling SIP ALG on a Thomson Router

Introduction

SIP ALG is used to try and avoid configuring Static NAT on a router. Its implementation, however, varies from one router to another, often making it difficult to inter-operate a router with SIP ALG enabled with a PBX. In general, you would want to disable SIP ALG and configure one to one port mapping on the router.

In this article, we will show you how to disable SIP ALG on a Thomson router. SIP ALG on this router is known to cause problems with VoIP calls. Proceed as follows:

  1. Open Command Prompt – “Start” → “Run” → type “cmd” and press “Enter”.
  2. In Command Prompt, type “telnet 192.168.1.254” and press enter. 192.168.1.254 is the default IP address of the router. If you are running on Windows 7/8/8.1/10, you might need to install the telnet client from “Control Panel” → “Programs and Features” → “Turn Windows features on and off”.
  3. The default username is “Administrator”, and there is no default password, leave blank.
  4. Type “connection unbind application=SIP port=5060” and press “Enter”.
  5. Type “saveall” and press “Enter”.
  6. Type “exit” and press “Enter” to exit the telnet session.

SIP ALG in now disabled on your Thomson router.

Notes

  • The SIP phones behind this router should be configured not to use STUN
  • The SIP phones must NOT be configured with a local port of 5060 or 5061. The local port of the phone must be changed to something else.
  • Configuring a SIP Phone behind a Thomson router might require port forwarding to be implemented on the router. So you will need to port forward the SIP and AUDIO (RTP) ports on the thomson router and point them to the SIP Phone’s IP Address.

Disabling Router SIP ALG

With many companies asking their employees to work from home, a common problem when trying to use a sip phone on a home network is the SIP ‘helper’ or ALG, Here is some advice on how to disable it on the more common routers that you may encounter.

SIP ALG (Application Layer Gateway) modifies VoIP traffic with the aim of solving NAT and firewall related problems. SIP ALG does this by inspecting SIP packets and modifying SIP Header and SDP data.

Unfortunately, SIP ALG was poorly implemented in a lot of cases, which has lead to it causing more issues than it corrects and due to this, we believe that, in general, it is best disabled.

Note – Many routers will re-enable SIP ALG after being powered off and on, or sometimes after a firmware update, therefore if it has been disabled in the past, and you know that the router was recently updated and powered off and on again, then it is always a good idea to log in to the router and double check the setting.

Virgin SuperHub: SIP ALG cannot be disabled in the settings of SuperHubs. Please click here for advice troubleshooting issues with SuperHubs. 

BT: SIP ALG cannot be disabled in the settings of BT HomeHubs, but can be disable with BT Business Hub versions 3 and higher:

Disabling a BT Business Hub 5’s SIP ALG

Fritz!Box: SIP ALG can’t be disabled.

DrayTek routers: Log in to your DrayTek via Telnet using an SSH client such as Putty: http://www.putty.org/

Check if SIP ALG is Enabled or Disabled:

To check if SIP ALG is Enabled or Disabled enter this command: sys sip_alg ?

If SIP ALG is disabled a ” 0 ” result will be returned.  If SIP ALG is enabled the result will be ” 1 “.

Disabling SIP ALG:

To Disable SIP ALG enter the following:

sys sip_alg 0
sys commit
sys reboot

The router will restart and save your changes.

TP-Link routers: How to Disable SIP ALG on TP-Link ADSL modem router

Linksys: Check for a ‘SIP ALG’ option, in the ‘Administration’ tab under ‘Advanced’. 

May also need to disable SPI Firewall. 

Microtik: Disable ‘SIP Helper‘. 

Netgear: Look for a ‘SIP ALG’ checkbox in the ‘WAN’ settings.

Port Scan and DoS Protection should also be disabled.

Disable STUN in VoIP phone’s settings. 

D-Link: In your router’s ‘Advanced’ settings –> ‘Application Level Gateway (ALG) Configuration’ uncheck the ‘SIP’ option. 

Huawei: Many routers support SIP ALG (usually found in the ‘Security’ menu). 

SonicWALL Firewall: Under the VoIP tab, the option ‘Enable Consistent NAT’ should be enabled and ‘Enable SIP Transformations’ unchecked.  

Thomson: How to Disable SIP ALG on a Thomson Router HERE

Test with STUN disabled in your VoIP phone’s settings.

Adtran Netvanta: Disable SIP ALG under ‘Firewall/ACLs’ –> ‘ALG Settings’.

For Technicolor TG588V routers see this document for step by step details

Even if there isn’t a SIP ALG option in your router’s settings, it may still be implemented. TelNet commands must be used to disable SIP ALG with TechnicolorThomsonSpeedTouch, some Draytek and some ZyXEL routers.
