PRI Qsig Link from Mitel 3300 to Avaya Red

[brogerson]

I have  a PRI QSIG link from a Mitel 3300 Release 6.0 SP3 to an Avaya Red.   Currently calls from an Avaya phone to a Mitel phone work fine but calls from Mitel to Avaya fail.

Last night a tech made a test call and he got a busy and all the channels were Idle.  When I do a CCS Trace while making test calls I can see the Mitel trying to make the call but the Avaya does not see the call.

Is the Avaya an IPO or CM?

Is this on an embedded PRI card? Use "EDT TRACE TSP L2L3 <PLID>" to watch the Q.931 messages and responses occur.
