VoIP – Per Call Bandwidth

These protocol header assumptions are used for the calculations:

  • 40 bytes for IP (20 bytes) / User Datagram Protocol (UDP) (8 bytes) / Real-Time Transport Protocol (RTP) (12 bytes) headers.
  • Compressed Real-Time Protocol (cRTP) reduces the IP/UDP/RTP headers to 2or 4bytes (cRTP is not available over Ethernet).
  • 6 bytes for Multilink Point-to-Point Protocol (MP) or Frame Relay Forum (FRF).12 Layer 2 (L2) header.
  • 1 byte for the end-of-frame flag on MP and Frame Relay frames.
  • 18 bytes for Ethernet L2 headers, including 4 bytes of Frame Check Sequence (FCS) or Cyclic Redundancy Check (CRC).

Note: This table only contains calculations for the default voice payload

Explanation of Terms

Codec Bit Rate (Kbps) Based on the codec, this is the number of bits per second that need to be transmitted to deliver a voice call. (codec bit rate = codec sample size / codec sample interval).
Codec Sample Size (Bytes) Based on the codec, this is the number of bytes captured by the Digital Signal Processor (DSP) at each codec sample interval. For example, the G.729 coder operates on sample intervals of 10 ms, corresponding to 10 bytes (80 bits) per sample at a bit rate of 8 Kbps. (codec bit rate = codec sample size / codec sample interval).
Codec Sample Interval (ms) This is the sample interval at which the codec operates. For example, the G.729 coder operates on sample intervals of 10 ms, corresponding to 10 bytes (80 bits) per sample at a bit rate of 8 Kbps. (codec bit rate = codec sample size / codec sample interval).
MOS MOS is a system of grading the voice quality of telephone connections. With MOS, a wide range of listeners judge the quality of a voice sample on a scale of one (bad) to five (excellent). The scores are averaged to provide the MOS for the codec.
Voice Payload Size (Bytes) The voice payload size represents the number of bytes (or bits) that are filled into a packet. The voice payload size must be a multiple of the codec sample size. For example, G.729 packets can use 10, 20, 30, 40, 50, or 60 bytes of voice payload size.
Voice Payload Size (ms) The voice payload size can also be represented in terms of the codec samples. For example, a G.729 voice payload size of 20 ms (two 10 ms codec samples) represents a voice payload of 20 bytes [ (20 bytes * 8) / (20 ms) = 8 Kbps ]
PPS PPS represents the number of packets that need to be transmitted every second in order to deliver the codec bit rate. For example, for a G.729 call with voice payload size per packet of 20 bytes (160 bits), 50 packets need to be transmitted every second [50 pps = (8 Kbps) / (160 bits per packet) ]

 

Bandwidth Calculation Formulas

These calculations are used:

  • Total packet size = (L2 header: MP or FRF.12 or Ethernet) + (IP/UDP/RTP header) + (voice payload size)
  • PPS = (codec bit rate) / (voice payload size)
  • Bandwidth = total packet size * PPS

The snow is coming – and don’t we all just love a snow day?

sledgingWell the school kids might, but for those of us with businesses to run, customers to service, and targets to achieve, the prospect of a heavy snowfall and not being able to reach the office can fill us with dread

The thought of a growing backlog of work can be stressful, but missed sales opportunities can spell disaster. In fact, in recent years, blizzard conditions have been said to cost the UK economy as much as £1.2 billion per day.

Fortunately help is at hand, with cyber-cottage.co.uk VoIP phone services, you can beat the weather by having extensions at home, routing calls to mobiles, using hunt groups and flexible voicemail (delivered to your mobile or email inbox).

You keep your normal business phone number, and what’s more, our business customers find that by switching to cyber-cottage.co.uk, they save their businesses money.

If you have any concerns at all about being cut off from your business during heavy weather, then I know that cyber-cottage.co.uk phone services will make your life easier, save you money, and prevent you from being cut off from your customers.

If any of the above could have an impact on your business then I would be very keen to discuss how we can help, and can reach me on 01225580025 for a no pressure chat about your options (whatever the weather).

For example over the cold snap in Jan 2013 we very quickly enabled a number that could be used by a large school so that parents could text in and the group of people receive the text content by email. This meant parents didnt have to call and wait to be answered or be able to send in an email. At school it meant that the message got to all the relevant people and not having someone huddled round one mobile phone and forwarding messages on.

Calls and Lines Connectivity

EFM Leased Lines

Highly reliable 20Mb symmetrical Internet from £350.00 per month

EFM Leased Lines (Ethernet in the First Mile) provides high speed, reliable internet connectivity for businesses who have outgrown traditional broadband, but where fibre base Ethernet services are still too expensive.EFM uses multiple copper pairs to deliver the service. These are bonded together to provide a combined service. By combining pairs you will receive a much more reliable service because if there is a fault with a single wire then the service will just slow down, rather than taking your business off line.In addition, unlike ADSL where the customer is typically responsible for reporting a fault, with EFM the service is proactively managed by the Gradwell operations centre and where a fault occurs, it is quickly spotted and resolved.Finally, if there is a copper wire fault in the BT Openreach network, EFM is provided with “Service Level 4” which aims to have an engineer resolve the fault within 6 hours.

To order EFM, you will need to contact our sales team. Orders are subject to survey and take between 25 to 90 days to be delivered. EFM is available in 1500 of the most popular UK telephone exchanges and you can be upto approximately 4km from the exchange.

To use EFM, BT Openreach will install a number of analogue copper pairs and associated wall sockets. In addition an EFM network adaptor will be installed, which provides you with an Ethernet socket. You will need to have a spare power socket available within 1M of the BT sockets.

Upgrading EFM

It is not possible to upgrade from 2 Pair EFM to 4 Pair EFM or vice versa. Should you wish to upgrade in the future, you would have to cease your line and reinstall.

We can allow some overlap of the circuits to ensure that you do not lose connectivity in these circumstances, but this may be limited to the number of pairs available as exchange capacity may have changed from the time the original order was placed to the time you wish to upgrade.

EFM Pricing

  • Gradwell EFM services are available on a 1 year or a 3 year contract
  • 3 year deal: 50% discount on installation fee
  • The first months line rental and installation fees are payable upon placing of order

Indicative speeds

Like ADSL, the speed an EFM circuit will run at will depend on your distance from the exchange. However, with EFM we can guarantee the minimum speed you will receive1. In our trials, we found that most customers receive a faster speed service than we can guarantee.

EFM is also a symmetrical service – meaning that both the upload and the download speed are the same. This is great if you are making Internet Telephony calls, using video, or sending / uploading large files to the internet.

Restaurant Booking Solution.

We have been working with a client on a Hosted restaurant booking solution, providing the CTI and call tracking systems. This was complicated by the simple fact that the booking system was a closed system by another supplier.

The system works by the restaurant diverting their line to a DDI number we provide that sends the call to the system with the destination matching a defined number for that restaurant when the call enters the system the relevant settings are looked up in a database and audio message file, IVR options and CallerID name are set and the call is passed to the IVR. The caller then chooses their preferred option, The call can be depending of the time of day be passed to the call centre for a booking to be taken on the restaurants behalf or the call is passed to the restaurant where in many a Hosted Gigaset Dect handset is provided for them to take the booking or call the call centre for free.

The system has changed and evolved over time and by using Asterisk has meant that we can accommodate most requests for changes, Most recently we updated the statistics package to Asternic Pro

Asternic stats
Pro stats

Statistics. This has allowed much more detailed reports to be created for queues and agents.

The calls are delivered to the platform over a EFM circuit from Gradwell.net providing quality and reliability combined with increased capacity over the original ISDN30 circuit.

For disaster recovery we provide a backup system in a data-centre that is kept in sync with the office system so in the case of power outage or system failure calls can be diverted to this system and calls take on mobile phones. Switching to back-up system is completed by the single click of a button on a web-page that instigates the diversion of the lines and starts the backup system automatically.

Currently we are migrating the database services off to a separate VMware server with 3 VMs, one for each of the core web or mysql servers. This will allow the service to scale as there are now over 1 million records per datatbase and it is showing no sign of slowing.

Outdoor pursuits company.

We were approached to supply  a hosted PBX solution to a Southwest England based Outdoor pursuits company replacing their on site AsteriskNow system with a more manageable and streamlined hosted Elastix based solution.

This gave them the ability to have handsets located where ever they were needed and add handsets easily with the user friendly Elastix interface. It also gave them increased viability of call usage with the inbuilt reporting and FOP2 let them see users engaged on calls.

We ported their existing BT Analogue lines to Gradwell VoIP trunks, This gave them an immediate increase in call capacity and combined with inclusive landline and mobile call packages meant call costs were kept under control.
