We are running 11.2.1.32 cluster and we are having very strange behavior in the BLF's on Grandstream, Snom and possibly other phones
They work very infreequently and sometimes just lock-up lit or blinking when the remote extension is not in use.
Transfers to extension using the BLF buttons dont work.
when you restart a GS phone the BLF's dont even start working until you dial the extension for the first time after reboot
We have the blf set as "extension-tenant" as instructed by TL for cluster systems.
We understand that the BLF's are handled differently on the clustered system and TL says they work with Yealink phones as they support different values for subscription and number to dial but this does NOT seem to work with other SIP phones that are supported by TL.
TL sent a changed config file for kamailio which helped the Snom phone a bit but the Grandstreams are still "out to lunch".
Any ideas???
Regards,
Andrew
