Hello Juha,
Related to your questions:
two questions:
- is info level message really necessary? i would prefer debug level
message.
Sure, it also sounds ok for us to decrease to debug level and we will do this.
- since there can be several (sets) of rtpengines running on the same
host as sip proxy, on private network, and on the internet, how can one force_send_interface parameter be enough?
You are right, in case of multiple rtpengines in different networks, connections to both may fail with the "can't connect to a RTP proxy" error message. However, force_send_interface parameter is optional and if you don't set it, the kamailio will select an appropriate socket and the behaviour will be as expected.
Suppose one has a PC with 2 interfaces connected to the same network and wants to force traffic going through a certain interface, this parameter is helpful.
Maybe in the future we could improve the functionality of this parameter; we are open to suggestions.
