I'm having some trouble turning with trunk monitoring while using an
outbound proxy.

While all other sip messaging (e.g. calls) respects the outboundproxy
setting, Options packets from setting qualify=yes do not. Asterisk
tried to send the Options message directly to the "host=" IP, instead
of the "outboundproxy=" IP as it should, verified with tcpdump.

I've done a search of the mailing list and didn't turn up anything relevant.
Is there a setting I'm missing, is this a bug, or just something that
won't work. It seemed appropriate to check here before I filed a bug
report!

Best Regards,
Nicholas Lemberger

Are you absolutely sure you need to use the outboundproxy setting rather than using a peer/friend?

I am sure I need outboundproxy Smile

We use Kamailio in front of our softswitch as a type of firewall and
because not all sip endpoints can set the headers such that they will
work with said softswitch. Calling messages (and calling!) work just
fine through the proxy - that setting just doesn't seem to be honored
by the qualify=yes messaging.

This isn't a particular problem, but when we setup backup trunks that
go through a different proxy, for redundancy without the monitoring,
it takes a fair amount of time before the calls go through while it
waits for the problem trunk to timeout on it's own.

We use opensips as a "type of firewall" as well and don't need to set qualify=yes.

As I said, I don't *need* to set qualify=yes for things to work. It's
just that trunk failover takes ~30 seconds. If the first/main trunk
in an outbound route is down, outbound calls just sit with dead air
for a ~30 second timeout before the next trunk in the outbound route
is tried.

With qualify=yes, if the trunk is down, asterisk will mark it as such
and will skip that trunk until it starts responding to the options
ping again.

the problem.
