[asterisk-users] Windows Mobile 6 SIP client: Remote host can't match request NOTIFY to call

[OCG Technical Support]

I'm trying to get my Windows Mobile 6 phone working as an asterisk client.
Overall things are working well. However, I regularly get the following
message:

 

[Nov 27 21:57:28] WARNING[4507]: chan_sip.c:12892 handle_response: Remote
host can't match request NOTIFY to call
'67aa8e223479055656161bf17ebb77d5 at 172.31.253.4'. Giving up.
