Hi OpenSIPs Community, I wanted to report an issue I discovered when attempting to use the rtpproxy module, using the dialog backed rtpproxy_engage() function. Finding that it was not engaging in certain scenarios I took a closer look at the activity on the control port and discovered that OpenSIPS never sent a request to open the session in this scenario.
To help illustrate, here is an example control port sequence of a properly engaged call: 65098_11 *UR*8.8.8.8c9,8,0,3,101,13 *the-call-id* 192.168.153.223 10248 *from-tag*;1 65118_19 *LR*8.8.8.8c8,101 *the-call-id* 192.168.153.223 10248 *from-tag*;1 *to-tag*;1 In my scenario the *UR* (create session) request was never received. Without claiming any expertise on the rtpproxy protocol this was clearly not correct and the *LC* (update session) request could not locate a session to act on. Following a fairly lengthy investigation I traced the issue back to my usage of the async() function where i was issuing the rtpproxy_engage() request before calling async for another purpose. The solution was simply to move the rtpproxy_engage() call to after the async method. I'm happy that the issue is resolved for my requirements however I thought I would share the experience to the list in case others found themselves having a similar issue. Thanks!
