If the audio is going directly there's not too much you can do to examine
it. There may be software out there to sniff the data on your network and
examine the RTP stream, maybe even see when it drops out (if it really does drop
out, ie: stream actually stops). I know there's some Windows software out
there capable of this as I picked a copy up while at Spring VON but you might
need to look around. OH - can you also send a sip debug with the reinvites?
I'm just curious to see the RTP information in the SDP.

Hey guys,

I'm having yet another strange problem. I've recently set
canreinvite=yes,
allowing the RTP streams to avoid our * server. Now, a few people are
experience one way audio drops on internal calls. External calls are working
fine (they re-invite directly to a Cisco router). Sometimes, if you wait 20
seconds or more, the stream will resume. Flipping the person on and off hold
won't resume the stream.

We're using 7960 phones. Enabled_vad is set to 0 (disabled). It doesn't
seem
to happen all of the time. There are no sip messages being exchanged when
the stream stops or restarts.

Any suggestions?

Thanks.
