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
The HT486 is a single-line device with a PSTN pass-thru. The only multiline IADs I know of are the SIPURAs and the Cisco ATA-186... What you do is you create 2 contexts, 1 for each line of the device and you set the host name to the IP address (or host name if applicable) of the IAD. Set the username of each context to the line's respective extension in Asterisk. Then in the web setup for the IAD, there should be a place to put the username for each line as well as the password... I have not tried this but it should work, SIP is not IP/MAC based it's more like SMTP, it's user based... -Chris

There are no standards that dictate an IP per line.
