Hi Anders!
Please post the corresponding syslogs of a failed INVITE.
You might also incrase the debug level (3 or 4, will blow up your syslog) and use
ngrep -d any port 5060 or icmp
to watch for looped messages and ICMP errors.

Thanks Klaus, I appreciate your help.
I did put step-by-step xlogs around my code and can see that the module sometimes picks a new IP to go to but most times it doesn't and hence no INVITE goes out.
I can't tie success or failure to any specific event. I have now tried this configuration in OpenSER 1.1 from yesterday's CVS tree with identical results.
Is anyone else seeing this issue?
Thanks.

Hi Anders!
I've never used the dispatcher module, but by putting xlog statementes after each function in openser.cfg will give you a hints what's going on inside openser.
log important paramters (request URI, dest URI) using xlog and pseudo variables and watch them in syslog.

Hi,
I haven't been able to get an outgoing INVITE for every incoming INVITE my dispatcher setup receives.
What I'm expecting:
When the first INVITE comes from 10.1.50.30 (Asterisk) to 10.1.50.31, (OpenSER 1.0.0 with dispatcher) I want to see an outgoing INVITE from 10.1.50.31 to one of the listed addresses. (10.1.50.[34-37])
What I'm seeing:
A tcpdump shows that most of the time (90%) all I see is the incoming INVITE. Seemingly random INVITES produce an outgoing INVITE. Presumably the only substantive difference being the CallID. Interestingly, all the outgoing INVITEs are addressed to the same IP. (10.1.50.36)
Am I not expecting the right thing? Can anyone shed some light on what I'm doing wrong here?
Thanks.

with no outgoing INVITE. Things seem to be dead. Then I try the same call a few seconds later and I get the outgoing INVITE, but always to the same IP (10.1.50.36)
