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,
Simplest (with 3-4 T1s):
Telco Lines -> Asterisk box with T1 card (and possibly a codec processor
card) -> Customer
More complex (with a bunch of circuits) :
Telco Lines -> Gateway T1 -> SIP Proxy -> Media Servers -> Customer
And if your question of "number of channels" is "Can I control the
number of channels a customer can use simultaneously?", then the answer
is "With Asterisk, Yes"
