[OpenSIPS-Users] RTPProxy duplicated SDP rewriting

[Seth Schultz]

Bogdan,

The reason I am doing this is because I have outbound call PSTN gateways on
both the LAN and WAN and these are in the same load balancing group.  The
gateway on the LAN needs to have rtp_proxy_offer("iir"), while the WAN
gateways need rtp_proxy_offer("ier").  So if I try on an external gateway
with rtp_proxy_offer("ier") and then it hits my failure route and the load
balancer picks the LAN gateway, then I need to have it use
rtp_proxy_offer("iir").

I guess I was hoping the unforce_rtp_proxy would clear it for the branch
and then I could do another offer.  To fix the issue I will just remove the
outbound LAN gateway for now.

Thanks,
Seth
