RE: BLF no work in Unify OpenScape Business
Hi Mario,

This is Evan from Yealink Support Team, nice to know you here!

This is a known issue. Yealink phones and Unify PBX are incompatible in the event type of BLF.

For Unify OpenScape PBX, the event type of BLF notify is keyset-info, it is a special signaling.
For Yealink or other brand phones, the event type of BLF subscribe is dialog or presence.

When the phones send a BLF subscribe with dialog out, it won't be recognized and access won't be granted. And the phone will get the 403 Forbidden from Unify server side.

For the present, we can’t support it, sorry. Is there any project that MUST need this feature ? Mandatory feature request?

Please let me know if anything I could help.

Best Regards,
