[asterisk-users] Extra REGISTER messages sent by Asterisk when subscribe for MWI is defined in zoiper

[Olli Heiskanen]

Thanks, there are no register lines in my sip.conf, but I have defined
callbackextension fields in the realtime table, to be the same value as the
extension name. In this case, extension 771 has callbackextension value
771. I tried replacing those with null values but that had no effect on the
outcome.

Currently when I register clients in, after some seconds Asterisk starts
sending REGISTER messages, at which point Kamailio sees 2 AORs, here's an
example:
(here 1.1.1.1 is the public ip of my server that houses Kamailio at 5060
and Asterisk at 5070, and 2.2.2.2 is the public ip of the network clients
are in)

        AOR:: 771 at testers.com

I guess there should be only one AOR, so Asterisk might get wrong kind of
data to begin with or it's configured incorrectly. In my sip trace the
REGISTER flow from client to Kamailio to Asterisk seems ok, I could be
wrong though.

In my setup clients authenticate with Kamailio and Kamailio sends a
REGISTER to Asterisk according to guide I used:
http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb

How would I fix this double-AOR problem, can it be fixed on Asterisk
configuration?

thanks,
Olli
