I setup an IP telephone Cisco CP-6921 and when the telephone authenticate in the server is logging a lot of lines like bellow with the method ‘REFER’
[Jul 3 00:02:09] NOTICE: res_pjsip/pjsip_distributor.c:649 log_failed_request: Request ‘REFER’ from ‘sip:email@example.com’ failed for ‘x.x.x.x:1024’ (callid: firstname.lastname@example.org) - No matching endpoint found
How can I disable that? this is set up in the .xml file?
I use other models of Cisco telephones and doesn’t have these packets.
