I am working with freepbx 10.13.66-20 and yealink t46g phones.
I am trying to get distinctive ringing working with these phones and have not been successful.
Default ring is set to long single ring
In the phone I have enabled distinctive ring
I have a DID set up for testing and have routed it both direct to an extension and a ring group.
In both the route and the ring group I have set the ring type to #2 which in the phone is a staggered tone.
The phone is not acknowledging the custom context and only rings the default ring tone.
I have also tried changing
Settings > Advanced Settings > Internal Alert Info
to change the internal ring with no luck.
