[Asterisk-Users] multiple lines with SIP like MGCP?

[Matthew Boehm]

We have a Dlink DVG-1120M and were surprised that it was able to handle 2
simultaneous conversations to 2 seperate phones using only 1 MAC address and
1 IP address.

So we asked ourselves..why can't other 1 MAC/1IP devices do this as well?

I have a Grandstream 486 that has 1IP and 1MAC. But I don't see anywhere in
sip.conf to add a second line to a device. Is this possible? Can this only
be done with an MGCP device?

Thanks,
Matthew
