[Asterisk-Users] DID Questions

[Kanuri, Seshu]

I agree with Mohammed. 

There are two ways to handle a 1877 call by the PSTN provider, when some one dials the number.

1) Teminate the call to another PSTN Number like 1-732-452-9222
2) By redirecting the call to a destination IP Address(i.e the IP address of a gateway) running similar protocol ex:SIP or H323
   In order to do this the PSTN provider has to convert the TDM call to a VOIP call with the required translation in the T1 PRIs of their VOIP Access Gateways, and then forward it to the destination IP.
   Check whether your provider can send it to your gateway as SIP call and not as H323 call, as all providers will not be able to terminate the calls as SIP. Most of the providers I know of are having Old CISCO AS5300/5400 equipment that can only translate abd send calls as H323.

Which device did you assign the 877 DID to? Because if you call that device
using another device registered to your asterisk box (i.e. your xlite
softphone) then its not hitting your provider at all.  The asterisk sees the
call come from a registered sip device and finds that there is a registered
device that has the assigned DID and routes the call to it, completing it.
However, when you call using PSTN, that's when the provider has to route the
call to your asterisk pbx. And it seems to me, they aren't doing that
properly.

Unless I'm totally not understanding what your trying to say but I've been
in these situations many times and its usually the provider's fault.

I'm using SIP and I'm not getting anything in the CLI when I call over
the PSTN. But over my Sip Softphone I can call it,  no problem.
