[Asterisk-Users] Intermittent SIP 404 Not Found response?

[Bruce Komito]

I have several SIP devices (Sipuras) that are working fine with *, except
for one annoying little problem.  Occassionally, after being registered
for some period of time, the Sipura returns a 404 Not Found to (I assume)
an INVITE request.  Of course, this makes the extension appear busy.
When this happens, I check the Sipura and it is thinks it is still
registered and I check * and it shows registered.  If I reboot the Sipura
or restart *, the problem clears.  It also clears by itself eventually.

Has anyone seen this behaviour and/or know how to cure it?

TIA
