Describe the bug

OpenSIPS 3.4 drops BYE because can not process stats from rtpengine. How it looks:

OpenSIPS 3.1 on same scenario:

In 3.4 logs we can see:

opensips[163545]: DBG:rtpengine:rtpe_function_call: proxy reply: d7:created
opensips[163545]: DBG:core:comp_scriptvar: str 20: route
opensips[163545]: DBG:core:destroy_avp_list: destroying list (nil)
opensips[163545]: DBG:core:receive_msg: cleaning up

In 3.1 logs we can see another messages:

opensips[1417169]: DBG:rtpengine:rtpe_function_call: proxy reply: d7:created
opensips[1417169]: DBG:rtpengine:pv_handle_rtpstat: no MOS found!
opensips[1417169]: DBG:core:parse_headers: flags=40
opensips[1417169]: DBG:rtpengine:rtpe_function_call: proxy reply: d7:created
opensips[1417169]: DBG:core:comp_scriptvar: str 20 : request_route
opensips[1417169]: DBG:tm:t_newtran: transaction on entrance=(nil)
opensips[1417169]: DBG:core:parse_headers: flags=ffffffffffffffff
....

To Reproduce

Just try to receive rtpstat from rtpengine.

Expected behavior

rtpstat will be processed, also OpenSIPS will pass BYE request through himself.

@kertor , how do you trigger rtpengine in relation to the BYE request? what script function do you use?

[kertor]

The issue is no longer relevant, as rtpengine_offer() was called twice in a row. We fixed the configuration, and now rtpengine_offer() + rtpengine_answer() is called. The problem no longer occurs.

Thank you!
