[asterisk-users] RTP ports used by Asterisk in dialplan

[ISABEL ORDAS ARNAL]

Dear all,

Do you know if there is a way to know the 2 RTP ports that Asterisk is using for audio flow in a call in the dialplan?
I would like to launch a Linux shell command "tcpdump" to capture audio flow in those 2 RTP ports before call starts and stop capturing at the end of the call.

Regards,
Isabel
