[b]Fisher,
If you had 24 trunks on a T1. That would only leave about 64 kpbs per line. That would be very low quality call won't it?
Are pretty much all VOIP products delivered in the form of analog trunks to a phone system.
I am not sure which system you use but in the Samsung line, if you use a TEPRI(T1 card) you can have the T1 go directly into your phone system and assign virtual (DID) numbers to transfer calls to different extensions instead of pointing the trunk.
This mean that you can have 1 T1 line and 100 different routing location as long as there are no more then 24 simetaneous calls.
I wonder if there is any such routing abilities with a VOIP product with either the ability to:
1. Be delivered in the form of a T1 with DID numbers which are virtual numbers to route the call to each extension.
2. Able to transfer a call to an extention based on the phone number(instead of permanately assigning a number to a trunk, and the trunk to the extension)
Thanks.
In the US all T1's are 24 channels x 64k = 1.54 Meg. When integrated circuits are put up here, ie NuVox's FlexLink product
www.nuvox.com, they bring in an Adtran to the size of the channels used for Voice. So if 6 voice and the rest data they bring in a Adtran 606, etc.
With VoIP circuits it's different entirely, since the codec usually brings the overhead down at about 20 - 30k per voice call. In this case NuVox has a dynamic allocation circuit product they call VoxIP and unless the circuit needs to be terminated to an analog 66/110 block they use a Cisco router. If it needs to be terminated to an analog punch down they use an Adtran device again.
And no I don't work for them, but have been talking to them recently about their offerings for a couple of clients.
As always, other than the fixed channel Integrated T1 in the first example, ie FlexLink product; mileage will vary depending upon the circuit provider.
As to the rest of your questions, likely. ;-).
Again implementations are specific to the circuit vender and their circuit offerings.
