Hey all, Has anyone ever had problems with flaky behaviour when registering softphones dynamically with asterisk? I'm working with Kphone and having problems getting consistent results with registration. When Kphone is able to register, asterisk reports -- registered SIP '2001' at XXX.XXX.XXX.XXX port 5060 where asterisk sees [2001] in sip.conf as [2001] type=friend username=2001 host=dynamic context=from-sip mailbox=2001 canreinvite=yes and the Kphone command window contains the entire, beautiful, SIP registration sequence. If I unregister or close kphone and allow the registration to lapse so that asterisk "sip show peers" replies with Name/username Host Mask Port Status 2001/2001 (Unspecified) (D) 255.255.255.255 0 Unmonitored and then try registering again, asterisk does not reply to the registration request. Kphone ends up timing out its REGISTER requests to the asterisk server without getting a single reply, and the asterisk CLI gives no indication of any activity at all. Does anyone know why asterisk wouldn't respond to requests? I have tried many combinations of stopping / starting asterisk and kphone, but there doesn't seem to be any rhyme or reason to the flaky registration behaviour. Thanks in advance, Jeff
