<DIV><FONT size=2>I have a similar problem with UT Starcom F1000g, after a while
it loses registration, sip show peers says its IP address is unknown. But the
phone still says it's registered, I can still see SIP packets and I'm able to
make a call from this phone. But if i try to call back, it dies with "Unable to
create channel of type 'sip' (CAUSE 3 - no route to destination)"</FONT></DIV>
<DIV><FONT size=2>This phone is known to give up if registration is not
succesful after a certain period, I believe its a bug in firmware but
manufacturer don't...</FONT></DIV>

SIP registration problem</DIV>
<DIV><BR></DIV>I have a Hitachi WirelessIP5000 phone (the original 1st gen
hardware). It's running the latest firmware (v2.2.6) and my Asterisk
server is running 1.2.10. This setup has been working great for me for a
long time, and then last week I started having a problem where the Hitachi
phone loses registration. It registers fine when I first power it on,
but at some point later the display shows "Not Register" and the phone never
attempts to re-register after that. The length of time depends on the
expire setting. If I press the "Register" soft key on the phone, it
re-registers fine, only to lose registration again later on. I have not
made any config changes to the phone. I have made some extensions.conf
changes on the Asterisk server, but I can't think of any way that would cause
this problem.<BR><BR>I did look at a packet trace of the SIP communication
between the phone and server. SIP registration expire is set to 60
seconds. When the phone first powers up, it sends a SIP REGISTER without
an "Authorization:" header. The Asterisk server replies with "401
Unauthorized." The phone immediately sends another REGISTER with the
"Authorization:" header included and succeeds. At 30 seconds after power
up, the phone sends another REGISTER without "Authorization:" and gets "401
Unauthorized" and then immediately retries, again without the "Authorization:"
header. At 60 seconds after power up, the phone's display changes to
"Not Register" and it never tries to register again unless I press the
"Register" key or power cycle the phone.<BR><BR>Anyone have any idea what
could be going on here? I have tried downgrading the phone's firmware to
v2.1.11 and had the same problem. I have not tried upgrading to a newer
version of Asterisk, but seems like that shouldn't be necessary since thing
were working fine before.<BR><BR>Any help
appreciated.</BLOCKQUOTE></BODY></HTML>
