[asterisk-users] DID from Direct from Telco

[Nick Khamis]

Hello Everyone,

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
need? Basically
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,

Nick.
