Yealink Forums

Greetings Team,

I am new to this forum & I apologize in advance if this has been asked before. I have a Yealink PBX system here at work & the IP phone model we use is SIP-T20P. All the extensions are working except one which isn't able to receive external calls. I've checked the configurations & everything seems alright. Is there anything I missed? I'd really appreciate your help in solving the problem.

Warm regards,

Michael.
