Please it is urgent. I have a call manager 5.1, and two 2821 gateway connected over IP.In the first site i have a Pbx Alcatel connected to one gateway, on the other site the CCM 5.1 The IP phones (IP communicator) are registering, and are able to call each other(the phones are ringing), but i can't hear any thing from the second site (ipphone to analog phone) when we answer the calls, i can hear the voice from the analog phone but not from the ip phone. but between ip communicator and analog phone every thing is ok.
Please advice urgently (maybe it is ports problem or ... ???!!) i have voice and data vlans and an ASA.
