Description:If bindaddr into sip.conf is on a ip alias (eg. eth0 is 192.168.1.1 and the alias eth0:1 is 192.168.1.5), the signalling works correctly on 192.168.1.5 (eth0:1) but the rtp flows from eth0, aka 192.168.1.1

I think that can be simply fixed in ast_rtp_new by passing also the ipaddr and so setting rtp->us.sin_addr to the ip.
if the ip is NULL, just work as usual.

or is better to add a bindaddr option also into rtp.conf?

I can write that small patch, just lemme know what could be the best way to handle that.

this simple patch add the param bindaddr=x.y.z.k into rtp.conf, in order to make rtp binding to a specific ip if needed.

please check it out. was written in 5 minutes, although seems to work here.

not specifying the bindaddr= param makes rtp work as usual.

we have now maybe 4 of these patch on the bug tracker... all diffrent.  Talk to kram so you can do it properly.

Okay update to latest CVS and see if that does it for you.  This method just has SIP use its bindaddress for calling the RTP.

I'm going to assume this fixed, you can reopen if it isn't.
