<br>
I am looking for a way to troubleshoot issues with TDM (E1) trunks<br>
with a provider.<br>
<br>
Currently with SIP trunks I am using tcpdump to perform packet<br>
captures between our gateways and the SIP providers IPs, capturing<br>
traffic on all ports, to include both the SIP messages and the RTP<br>
stream.<br>
<br>
How can I achieve a similar result on TDM links connected to TDM cards<br>
in Asterisk servers, where by I can see the signalling (like the SIP<br>
message) and the audio stream (like the RTP stream) in my packet<br>
captures?<br>
<br>
If it helps, the end goal is to create something like the packet<br>
captures I am making so I can see the control signals and audio<br>
streams (in and out) for troubleshooting one way audio issues for<br>
example. So, am I sending audio to the TDM provider, are they sending<br>
it to me, have we both signalled correctly to start/stop sending<br>
audio, etc.<br>
<br>
Many thanks,<br>
James.<br>
