My setup is such:
192.168.0.10 (initiating and closing UA)
192.168.0.52 (proxy)
192.168.0.90-91 (gateway and receiving UA)
I set up the BYE to use the lcr routing and it seemed to behave itself
the 200 OK went through to start the call. Then the agent (i'm using sipp on
both sides)
sent back an ACK and a BYE. However, the odd thing is that the proxy sent the
ACK over to the from_uri domain, in this case 192.168.0.51, instead of sending
it off to the gateway/receiver at 0.91.
I looked in the logs and found that t_relay() had decided that there was no
active transaction and so i'm guessing it tried to find the best place for it..
which was the from uri i'm guessing.
That I guess is okay.. I'll have to find a way to keep the requests forwarding
to the proper gateway.. any input is appreciated.
Then the proxy went and did something really strange, it sent an INVITE to the
receiving UA. According to ngrep, it was not relaying any messages from the
initiating UA. It just sent it.. I have no idea why its doing that.. then
things kinda go downhill from there.
Anyone know why it would be doing this? Help would be appreciated. (logs and
route script below)
