I have two countries where I am trying to pass DTMF out-of-band with an Avaya switch.
I am told by TAC that they are passing the DTMF out of band, but I cannot see that in sniffer traces.
Has anyone else encountered this problem? What did you do to fix it?
Sorry - Additional information:
Using Cisco AS5300's in both countries. IOS Ver: 12.2(15)T10. CLAN 11.5 and Medpro 72 on Avaya.
