We are facing Caller ID problem in one of the Yealink IP Phones T20P models.
When the “Caller” calls the “Callee”, the Extension name is not displayed on the “Caller” side whereas on the “Callee” side, the Caller ID and Name is displayed. As per client, this was working in FreePBX but the same thing is not working in GS UCM6208.
Anyone facing this issue?
I have tried LDAP feature on GS IP Phones which works but some models like T20P doesnt support LDAP.
They have XML feature but there’s no configuration on IP Phone for such.
