Michael L. Young commented on ASTERISK-20805:
---------------------------------------------

Bryan, Glad to hear that it is working so far.  Once you test on the dual homed system and confirm that it is working, I will put it through the process to get it into the code base.

Thanks

> When sending a SIP Notify 'check-sync' to our IP331 phones, the FROM portion of the Notify message does not contain the IPv4 address of the Asterisk server's interface (to which the phone is registered).  The FROM instead contains something that looks like an IPV6 localhost address: 
>    From: "Unknown" <sip:Unknown@[::1]>;tag=as567b56ba
> The phones will not reboot, as the from message is not giving the server that the phone is registered to.
> This can be worked-around by putting in the interface's IPV4 address in the bindaddress field.  The FROM then looks like this:
>     From: "Unknown" <sip:Unknown at 172.16.99.218>;tag=as60768d2a
> This message does cause the phone to be rebooted.
> Unfortunately, setting the bindaddress will break any environment where SIP is used on two or more NIC interfaces.
> I believe that the Asterisk server should determine the IP address of the egress NIC interface (or the IP address that the phone is registered to) and place that in the FROM field in the SIP Notify message.
