Hello,The phone send 406

Hello,

The phone send 406 unacceptable message for the INVITE send by the CME.

This issue is similar to bug CSCug37105:- https://tools.cisco.com/bugsearch/bug/CSCug37105/?reffering_site=dumpcr

In the INVITE, the line "Accept-Language: ru;q=0" may be causing the issue,  the phone not understanding the header and not processing/discard the INVITE.


>> In order to remove this header, configure a SIP profile on the router.
Router(config)#voice class sip-profiles 100
Router(config-class)#request invite sip accept-language remove

>> Then we can applied this profile globally.
Router(config)#voice serv voip
Router(conf-voi-serv)#sip
Router(conf-serv-sip)#sip-p
Router(conf-serv-sip)#sip-profiles 100

 

Also please note of another bug CSCum05299:- https://tools.cisco.com/bugsearch/bug/CSCum05299/?reffering_site=dumpcr, can cause calling issues with SIP Phones.

Workaround, configure “no ip address trusted list”  and “no ip address trusted authenticate” under “voice service voip”.
