[Asterisk-Users] Multiple SIP registrations for one account?

[Cees de Groot]

Hi,

For various reasons a customer of mine is moving from a SER-based to an  
Asterisk-based installation, mostly because of problems with SIP devices  
behind NAT trying to reach each other and because it's easier to do  
accounting when all calls go through Asterisk (canreinvite=no is the idea).

The database-based SIP registration mechanism of Asterisk seems to have  
one shortcoming - it only allows one registration per SIP account, whereas  
SER has a separate 'subscriber' and 'location' table, allowing more than  
one registration; all SIP devices under the same account then ring  
simulataneously until the first one is picked up.

Is there by any chance some patch floating around that allows Asterisk to  
do the same? Or is it possible somehow to run this through SER+Asterisk  
(i.e. multiple registrations but the calls, both signaling and voice  
streams, must go through Asterisk)?

TIA,

Cees
