Cannot Recieve External Calls

We are able to make external calls as well as make and receive internal calls.

We are running FreePBX on Asterisk 1.8.5 with Polycom 331’s using SIP 3.3.1. Our gateways are Cisco 2951’s with dial peers defined as follows for our test extension, 8275:
dial-peer voice 4 pots
trunkgroup primaryTDM
description Inbound calls from Integra
destination-pattern [2-9]…
incoming called-number …
forward-digits 4
dial-peer voice 8275 voip
description Gateway to Asterisk
destination-pattern 8275$
session protocol sipv2
session target sip-server
voice-class codec 1
no vad

Call Logs show:
21. 2012-01-24 07:20:17 SIP/148.18… 7753366400 7753366400 s ANSWERED 00:12

Trunks in FreePBX are setup as:
Name=CiscoGateway; Outbound CallerID=“Washoe” <7753366400>; CID Options “Allow Any CID”; PEER Details are

Outbound Route ~
Dial Patterns:
Trunk Sequence is CiscoGateway

Inbound Route for 8275 is:
DID Number: 8275
Destination: Extensions - 8275

Extension 8275 uses Inbound DID 8275
We do not use secrets at this time (ie blank)
deny & permit both equal =
Optional Destinations go to Voicemail for 8275

Digit Maps for the Polycom 331 templates are: [2-9]11|0T|9011xxx|*[2-9]xx|*80[2-9]xx|9[2-9]xxxxxxxxx|[2-9]xxxT; Timeouts = 3|3|3|3|3|3|3

We are not in a position to rollout all our phone lines at the same time. Only one extension at a time.

I have not been successful in receiving any results when searching subject content.

At this point, there isn’t any agreement as to whether this is an issue with my FreePBX settings, the Cisco router guys configs, or the TDM guys configs (using an archaic ASPA program designating and extension as a station or an LCR). Everyone is pointing to the other. ;[

If anyone can confirm or deny my setting are correct or incorrect or lacking something, I would be very very grateful. I no doubt have missed providing some pertinent info. So please feel free to request whatever you might need (ie an Asterisk log dump, which I can’t really make sense of).

Thank you for your help!

qualify=yes&no makes no sense, it’s one or the other.

you also need insecure=port,invite for an unauthenticated inbound.

context also needs to be from-trunk to use inbound routes.

Changing/adding these parameters resolved our issue for extension 8275. I’m still thumbing through documentation to better enhance my knowledge of these parameters and their impact. Thank you again for your time and assistance. :slight_smile:
