There is not a way to do that on a per call basis.

Hi all,
I know you can set the upper/lower RTP port limit in autoload_configs/switch.conf.xml but, is it possible to have an upper/lower limit set and change it for a specific call?
For example:
switch.conf.xml has:
<param name="rtp-start-port" value="16000"/> <param name="rtp-end-port" value="32000"/>
We have certain clients that require a VPN connection to reach our servers, and the VPN blocks all UDP traffic from ports >10000.
One solution would be of course just to lower our range, ok... But is there a way that I can set the RTP port range for a specific call?
Something like this in diaplan:
[...] <action application="set" data="rtp-start-port=3000"/> <action application="set" data="rtp-end-port=4000"/> [...]
I don't know if this is doable some way... If FS doesn't have this option, maybe with a Kamailio + rtpengine in front we could potentially achieve this?
Thanks!
Best regards, Joel.
