I have a user who wants to see all inbound calls come in with only light flashing and all internal call to ring the phone.
This all works fine, except when a call is transferred from an inbound trunk. My Alert-info string “external” is not changed during transfer and hence the phone will not ring. I asked my friend Google, and all he could tell me is others are having the same issue and an attended transfer is the only way to change the alert-info tag. This does not work for me with all GXP2100 Grandstream phones.
Is this something I have to live with, or is there a workaround/fix for this?
I’ll appreciate all comments and help,
