FWD uses SER before Asterisk, so the initial SIP communication is always 
handled by SER.

See erlier messages on this list. SER (a SIP proxy) will ring all 
registered phones, and the first one picking up will win. 

On the other hand Asterisk (a PBX) will ring the latest/newest (?) 
registered device only, and with the refresh times being adjustable it is 
pretty much unpredictable which device will finally ring.

Bottom line: Multiple logins are ok with SER, and not ok/not advisable 
with Asterisk. Use queues or different logins if you need this 
functionality in Asterisk.
