I'd like to use the 2 analog lines on a Arris TM602G (DOCSIS 2 CM/MTA with battery),
with SIP firmware. (ARRIS-SIP-MIB)
I'm using the Asterisk 11.13.1 server from Debian, running on UDP port 5060.
When I use the same login and password for both port, it works most, but not all the time.
(I can make calls from both lines, but the second line doesn't always ring when called.)
I've also tried using a different account for the second port (such that I could use a different DID),
but Asterisk gets confused by having two accounts at the same IP address / UDP port.
On a Linksys ATA, I could set the second line to use a different source UDP port and then it worked fine.
Is there a way I could do the same with this modem?
Or some other way of getting to work?
ARRIS-SIP-MIB doesn't seem to have a way of setting the client UDP port.
We do this same thing all the time, with 2 line, 4 line, 8 line Arris talking to Asterisk
Provision each line with a unique DID / username
I dont see why Asterisk should get confused about this?
Are you using any NAT between the Arris and Asterisk?
