I have a setup where in sip.conf the host=ser.zxy.com for the phones. Non of the phones are connected to Asterisk directly, but are connected to SER. Thus non of the phones registry with Asterisk. I have noticed that when I forward a call to Asterisk it doesn't send the call back to SER (which is very good in my scenario). I was wondering if this was intended behaviour for Asterisk, that a call only gets sent to a phone if its registered (e.g. this behaviour wont change come the next version of Asterisk) ? The reason I have set host to SER is so that the MWI is sent to SER, but I don't want a call sent from SER to Asterisk to be sent back to SER. Thanks -- Shaun
