Here is the scenario. The customer has a CM 12.1.1 at the MAIN location and a DEFINITY 4.8.0 at FACTORY site. They are connected with old school DCS on a T1 (not PRI). Calls work great both directions.
The customer added a new location with a Shoretel system. The connection between Shoretel and MAIN is QSIG. Calls from Shoretel to MAIN work great and vice versa. However, calls between Shoretel and FACTORY fail in both directions. MAIN should be acting like a tandem switch but it does not work.
If I make a test call from Shoretel to MAIN I see the system send 4 digit extensions on a list trace and the call goes through. If I test across the MAIN-FACTORY link, I see the 4 digit call go through on the DCS trunk group as well.
If I list trace either the Shoretel-MAIN trunk group or the MAIN-FACTORY trunk group while dialing from Shoretel to FACTORY, the system sends 4 digits and immediately disconnects. I am not seeing an error code.
The phones at FACTORY are UDP extensions in the MAIN switch using AAR to get routed.
I believe I'm missing some programming to make the call tandem through. I have played with the tandem routing table, route patterns, etc.
As a test, I made a small vector in the MAIN switch to collect 4 digits and route to the number. If I call that vector's VDN from Shoretel and insert the digits for an extension at FACTORY, the call goes through so I assume it is not a trunk-to-trunk issue.
Any ideas or suggestions?
