Hello Juha,
Related to your questions:
two questions:
1) 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.
2) 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.
