T27 cannot dial from history
I have the following issues with Yealink T27P firmware

If a call is received, the Caller ID is shown as expected, for example 7032620001.

If I go to the call history to make a ringback, however, the phone tries to dial 7032620001@ which is the internal IP address of the asterisk server that sent the call to the phone in the first place. Note that the asterisk server is remote in a data center behind a Kamailio server. Anyways the phone fails to dial the number and says: Unknown URI Scheme and generates a busy tone.

I already used the following line in the config file (although I cant confirm its set in the GUI) with no luck:
custom.features.redial_via_local_sip_server.enable = 1

I need help as we have deployed a lot of these phones and we are getting a lot of support calls.
