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)"
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...

Subject: [asterisk-users] WirelessIP5000 SIP registration problem
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.
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.
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.
Any help appreciated.
