Scenario -
G450 with DS1 PRI to carrier. Carrier is delivering SIP trunk to ADTran then handing off PRI interface. On outbound calls...sporadically and almost always when an AA answers on other side we are seeing a # being added into the call via "list trace tac". This is then causing issues with the far end AA that answers. I can replicate this and it isn't specific to channel, time, user etc.
We replaced the PRI card. We replaced the MM717 Digital pack and it still does this. It does it on IP phones, digital and analog.
Thoughts?
