I am having some trouble with the *2 Feature code attended transfer.
Attended transfers work fine when calling directly to an extension or when I make a internal call. The trouble I am having is when the call comes in to a ring group from the IVR. When I pick up the call and dial *2 the dtmf tone is just played down the line and no Transfer message is played to me like it does with a direct call.
Could this be a configuration issue with my pbx or is likely to a be problem with my handsets?
I am currently running Asterisk Now 11.2.1 with FreePBX and my phones are Grandstream GXP2010’s running the latest firmware.
