I have an avaya 8700 connected to a nortel 1000M rls 6.0 software via a QSIG trunk. I'm having a helluva time getting theis thing to work as I thought it should. I can dial extension to extension without a problem. I cannot make an extenernal call through the nortel using an Avaya phone. On a nortel phone If I access the trunk shouldn't I just have to dial another 9 and the seven of 11 digit number to make an outgoing call. or do I have to use the maintenance set to test from the tn.
