[OpenSIPS-Users] rtpengine_delete not returning immediately

[John Quick]

Callum,

Thanks for the suggestion. I added a rule to iptables on the OpenSIPS server to allow all UDP from the rtpengine server.
Unfortunately, it made no difference. I also checked the route using mtr and it looks fine - less than 5 ms latency, 1 drop in >4000.
Network connectivity seems unlikely to be a contributory factor because the offer and answer commands work exactly as I would expect.
Only the delete command exhibits a delay returning.
