[Asterisk-Users] Failover Problem

[Brent Torrenga]

Doug,

I think I have seen this - does the initial invite to pbx2 make complete
sense - is it valid according to the sip.conf entry on pbx2? In the pbx2
sip.conf, try insecure=invite, maybe insecure=invite,port/insecure=port. I
don't have a real handle on why, but I recall it solving some sort of
similar behavior I saw, though it was in a different situation.

I think I had 2 * servers talking to each other like your phone and pbx2:
when someone tried to dial a sip URI to the second asterisk server using the
first asterisk server as the outgoing proxy.

>I have a weird situation. A polycom phone is configured to use system pbx1
as the primary outgoing 'proxy', followed by systems pbx3 and pbx2. All
three systems have identical sip.conf files. The phone is registered on
pbx1.
>
>I shut down the Asterisk application on pbx1. I make a call. The phone
sends an INVITE to pbx2. Pbx2 sends back a >407 Proxy Auth message to the
phone. The phone sends an ACK followed by the INVITE with the credentials.
What does >Asterisk do? It sends the 407 Proxy Auth message AGAIN. Why? The
phone of course re-sends the INVITE with the credentials again, and of
course Asterisk sends the 407 again. WHY?

>It looks like an Asterisk problem. As far as I can see, the phone is doing
the right thing. Asterisk should not be >sending Proxy Auth required over
and over again.

>This problem completely invalidates any sort of Asterisk redundancy. If
this doesn't work, Asterisk can't be used >in a redundant configuration, and
that's a deal breaker.

>Has anyone reading this done this before?
