Unlike going through DIDx, DIDLogic etc.., we have an option of
getting DIDs directly
from local telco Bell Canada. Currently our SIP Trunk provider
assigned a DID to us,
and as you know, they just redirect requests it to our PBX.
However, when dealing directly with a telco, what equipment will we
giving us the same capability as a DID provider. If someone can paint
a picture on how
the DID suppliers function it would be greatly appreciated.
If I were to guess it would be:
Telco Lines -> Gateway E1/T1 -> SIP Proxy -> Media Servers?
With this scenario, do we now have control over the number of channels?
Thanks in Advance,
