I am experiencing one way audio issues with hard phones (7940 series); only when making internal calls (users on the network), the called party can not hear the caller party, the caller can.
There are not problems when making external calls from the same phones that is no audio problems if i call a pstn line from the hard phones. Also no one way audio issues in internal or external calls between soft phones (Cisco IP communicators)????
Can any one please shed some light to what might the problem be???
