I have a wierd problem:
I have a GSM module and all incoming calls are pointed to an extension 211.
Now I set on my extension 211 (Grandstream phone) redirection to 212. So every incoming call should be ringing on 212. But there is some error:
Called PJSIP/211/sip:211@<phone_IP>:5060 > 0x7f4c38107810 -- Strict RTP switching to RTP target address <GSm_GW_IP>:8038 as source == Using SIP RTP Audio TOS bits 184 == Using SIP RTP Audio TOS bits 184 in TCLASS field. == Using SIP RTP Audio CoS mark 5 -- Connected line update to PJSIP/GSM-00000054 prevented. -- Now forwarding PJSIP/GSM-00000054 to 'Local/212@from-internal' (thanks to PJSIP/211-00000055) -- Not accepting call completion offers from call-forward recipient Local/212@from-internal-0000007a;1 -- PJSIP/211-00000055 Internal Gosub(app-missedcall-hangup,211,1) start
Why it is Not accepting call completion offers from call-forward recipient Local/212@from-internal-0000007a;1
What does it means and please what should I do to fix that?
Thanks for advices
