Can't hear calls.

Can't hear calls.

Can't hear calls.

(OP)
I've got an issue where throughout the day (it's very random)some users cannot hear the other end of the call and these are extension to extension calls. I'm new to Mitel and I have a 3300 MXe III and the handsets are a mixture of 5304's and 5312's. Everything else on the network works as expected without any issues. So I'm stumped as to what to check for on the 3300 to make sure everything is proper. I'm not the phone guy, but having to troubleshoot this since he is out of town. There doesn't seem to be a problem with external calls, only in-house.

RE: Can't hear calls.

are they all within the same network ?
are they in a voice vlan (seperated from data)

with Mitel voice is peer to peer , signalling is always via the Pabx
if the trunks are ISDN or PSTn based then that voice will be proxied via the Pabx address

No speech or 1 way speech is almost always routing or firewall related

If I never did anything I'd never done before , I'd never do anything.....

RE: Can't hear calls.

Sounds like a routing /gateway issue.

If phones are on different networks/vlan, easiest way to do a trace dump and see COnnection Information on the trace.
As Billz66 stated, RTP streams from handset to handset, so as longs as there's routing between the handsets and RTP ports are open, you should not have any issue.
RTP on external calls are different as RTP is anchored.
