[sr-dev] Make some commands in kamailio rtpengine module asynchronous

[Aditya Gupta]

We have 2 rtpengines in production and thousands of calls coming in. Few of them get timed out because they don't get processed in time by rtpengine. Simply by making 3 commands; offer, answer and delete. It can help us a lot with this.

I think I've understood what needs to be done and, in a day, or two I'll raise a PR with the changes for rtpengine module.
After that I guess there are some changes that needs to be done in sipwise/rtpengine media servers which seems complicated at this point.
I'm hoping for your support in improving my PR for now. Against which branch should I raise my PR??

Thank you

Hello,



what is the motivation behind this? Are you seeing performance issues in a production environment that could not solved e.g., by adding some more rtpengine resources?



Regarding implementation, you could also have a look for example at the http_async_client module, which might be a bit more easy to understand regarding the async implementation in Kamailio.



Cheers,



Henning

Hello!

We needed some commands in rtpengine module to be asynchronous that is offer, answer and delete. I needed help for this.



Firstly, I went through the evapi module to understand how asynchronous commands were implemented by suspending request/responses and then by continuing. But I couldn't see anywhere where the suspended commands were being continued.



Thank you.
