When I call a 7965 phone on a Call Manager Express system in another city from an Avaya IP phone call setup appears to be successful. The phone rings, the person picks up. But then an odd thing happens. They can hear me speaking into the phone - but on the Avaya phne can not hear a thing. I need the Avayas a few months more and then we'll dump it for full blown CCM.
Anyone have any thoughts how this half-working solution might have come about? CME calling other offices on CME is fine. CME calling out to PSTN via the Avaya is fine. Even CME calling the Avaya phone via IP is fine. Just the Avaya phone calling the CME 7965 results in the half-a-conversation.
