I played with the 1204 about a year ago. The 1204 firmware at that time
required me jump through hops to get it to work. As I recall, we had to
define a 'callerid' number in asterisk for each port of the 1204 that we
wanted to direct traffic to, and then on the 1204 define something that
essentially said... if the callerid from asterisk was '1111', then route
the call via pstn port 1. If the callerid was '2222', then route to pstn
port 2, etc.
I don't have a clue whether that approach is still required with their
newer firmware.
At that time, the 1204 worked very well. But, the irregularities of their
firmware was far more then enough to make me return the unit to the
reseller.
