Xlite & CISOC IP PHONE 7942 with Asterisk

Hi ! everyone !

I configured a Xlite client and IP PHONE Cisco with asterisk in local network.
I can called from my Xlite client to IP PHONE Cisco but from Cisco IP Phone 7942, it doesn’t works !
I’ll get this error from Asterisk log when I tried to make a call from my Cisco IP Phone 7942, if someone can tell me what’s wrong with my configuration ?

NOTICE[3347]: chan_sip.c:22718 handle_request_invite: Call from ‘client-3’ (192.168.1.158:51662) to extension ‘5’ rejected because extension not found in context ‘users’.

regards

Asterisk is only receiving the invite with the number 5 and it is telling you that you don’t have an extension that match only ‘5’. So I guess is a problem in your phone’s dialplan so you may check it.

Thanks for your help navaismo ! I’ll check it right now !
