Hi FreePBX Community,
first of all: I am total Newbie, not only to freePBX but also to SIP in general.
I have managed to set up a freepbx, connected it to a sip trunk provider and set up some extentions.
Now the problem: “Attendended Transfer” works well when i use “Feature Transfer” using the DTFM Codes *2 <ext_number>, talking the *4
But Transfers Using the Buttons on several (different) Yealink Phones does not work at all.
As soon as i press the “Tranfer” Softkey, the caller hears silence. If (after talking to the person who should get the Transfer) i press “tranfer” again, the Yealink Phone says “Transfer completed” but the caller is left in Silence and to the person who should get the tranfer it seems as if i had terminated the call.
Unfortunatly i do not know what logs i should provide.
Yours Gerd
