ISDN Switchoff…

With the end of ISDN looming, the switch off could affect over two million businesses in the UK which will come at a cost for those affected. For many, the cost implications to replace their entire Telphone system would simply be too much, but with Sangoma’s offering, the transition from PSTN and ISDN to VoIP can provide a long-term, cost-effective solution.

Why remove a PBX that gives you everything you need? Sangoma’s Vega Gateways provide seamless connectivity to SIP providers, with no need to change any existing hardware or to re-cable your system, these gateways are designed to migrate from PSTN to SIP with minimal downtime.

Available in a range of varieties, Sangoma Vega Gateways suit businesses of all sizes from the SME to enterprise corporations. What’s more, users can benefit from advanced functionalities such as least cost routing (selecting the cheapest route for a call) and enhanced network proxy features which can help with the failover of calls from VoIP to PSTN in the event of a loss of internet connection.

If you would like more information or advice on what is the best option for your business please call or email us. Unlike many we have ISDN simulators so that we can configure your new gateway and install it with limited disruption to your business

Vega VoIP digital gateways

The Most Resilient VoIP Digital Gateways in Their Class

Vega VoIP digital gateways are small appliances that seamlessly connect your legacy telephony infrastructure, made up of PRI (T1, E1) or BRI lines, to IP networks. They are great for businesses with legacy phone equipment (such as a TDM PBX) who want to connect to SIP trunking services without having to spend money altering their current network infrastructure. They are also great for businesses that are already VoIP enabled at the core (with an IP-PBX) that need PSTN connectivity and require a SIP-to-TDM converter. Simply place the Vega VoIP Digital Gateway at the edge of your network, plug in your existing internet cable for VoIP connectivity and E1,T1 or BRI cables from your phone system and let the Vega VoIP Digital Gateway automatically handle the SIP signalling and voice media conversion for seamless voice and T.38 Fax integration.

Advanced Web GUI
Features an intuitive Quick Wizard which does all the hard work for you for new deployments. Flexible dialplan to allow you to make your own routes, including automatic failure detection with failover routing.

Diagnostic Tools
Web GUI based PCAP tracing tool to capture full signaling and media, eliminating the need to connect equipment for line tracing, fully compatible with wireshark.

Low and High Density Models
The Vega 100G and Vega 200G are our low density models with a maximum capacity for 30 and 60 SIP-TDM simultaneous calls. The Vega 400G is our high density model and the most flexible field upgradable unit for a maximum capacity of 120 simultaneous SIP-TDM calls.

E1/T1 & BRI Interface
Each E1/T1 interface (for Vega 100G, 200G, 400G) and BRI interface (Vega 50 BRI) can be independently configured as network side or terminal side. The Vega gateway can therefore be connected to a PBX or the PSTN.

Built-in Local Survivability
In the event of a WAN failure, IP phones behind the Vega gateway can continue to call each other, be routed to a backup switch or connected directly to the PSTN.
