How I can pick the brain of the community; I am pretty stumped
= WebSocket connection from 'xxxxyyy' for protocol 'sip' accepted using version '13' -- Registered SIP '1080' at xxxxyy:zz == Using SIP RTP CoS mark 5 [2018-04-05 06:40:35.377] NOTICE[C-00002761]: chan_sip.c:26219 handle_request_invite: Call from '13cb1pmt' (xxxx) to extension '0xxxxxyyy' rejected because extension not found in context 'office-main'.
