Hey there,
Setting: 2 phones (7962's) connected to POE switch (3750) which has a link to 2911 running SIP CME 9.0...
State: Both phones register perfectly with newest SIP code.
Condition: 1 out of every 3 call's from either phone to the other fails... no ring on the destination phone... So one call works... call completes, 2 way talk path, then hang up and redial, and no ringy... Is this potentually a DTMF relay issue? I have dtmf-relay sip-notify enabled on all pools...
Ideas?
