With these two basic requirements I can give back to you (dependent on broadband connection speed), up to twenty simultaneous external calls.
How is this accomplished?
We can explain best by using a standard call and the clients network shown on the previous page.
The bandwidth requirement for a g729 codec call (the equivalent of a standard PSTN call) is 34K.
My client is running 21 snom320 IP handsets via an Epygi Quadro 4x4. Connection is made through a dedicated Iinet Business Grade ADSL2+ VoIP Service.
An ADSL2+ Service has a current maximum speed of approx 24000K down and 1000K Up.
An Epygi Quadro system using the 729 law codec (equivalent to a standard Telstra PSTN call) uses 34K of bandwidth per call. 20 lines at 34K uses a maximum of 680K. Well under the 1000K limit.
Lets compare the price for 20 lines ………………
Telstra PSTN Services:
Rental at $19.90 permonth X 20 lines (Telstras best price) is $398.00 per month. No calls included.
Peninsula Telephone Services:
Rental at $6.95 per month for all lines.
Thats leaves $391.05 in your pocket each month or $4692.60 per year. That’s a lot of calls!
ALL WE NEED IS A RELIABLE INTERNET SERVICE COMBINED WITH A RELIABLE DATA NETWORK!
