call dropping in middle of converstation

Hi,

I have an issue between a Cisco AS5400 and Mitel phones. Randomly in the middle of a conversation the outbound voice seems to drop. We can still hear the person on the other end of the phone, but they cannot here us. We have two E1 as out outbound trunks. Any ideas?

Cheers

Recent version, still I would try upgrade to 12.4(latest) and if still present begin with debugs to identify on which conditions it happens/.

Hi,

Cant help you directly, however I've been working on a very simular problem myself for the last 2 months. My problems are from Cisco IP phone to Ip phone, and from IP phone to PSTN world where the RTP stream simply drops half way through the conversation. A workaround I have found is to press then press again the hold button (ie put the caller on hold then release) which re creates the RTP stream. My problem seems to happen more after a conversation lasts greater than six minutes!!!!!!

We binned the Mitel phones and replaced them with Linksys. We have not had any issues since. I will never go near a Mitel phone again. Huge waste of time and the support for them is very poor.
