We have setup AlertInfo for incoming calls that go through a ring group, to sound different than other calls, mainly between inhouse phones.
The issue we have with this setup is, when we receive an incoming call, it rings the unique audio, we answer, then when we transfer the call to a single extension, it still rings at the other extension the first ringtone, instead of the inhouse ring.
My guess in this situation is, the AlertInfo is staying with the call and not clearing after being answered from the ring group.
I tried looking for a Transfer AlertInfo, or anything related, that would reset or clear the alertinfo, but to no avail.
Server is FreePBX, about a year old, I’m not certain of the specific version. All phones are Grandstream GXP2170.
