Hello Community,
please help me with a problem with blf on Snom phones.
We are using Snom D765 with FreePBX in Version 14.0.13.6.
BLF works directly after booting up the phones as expected. After 1 hour the blf function stops working.
While it is working we can see all extensions on subscriptions.htm. After settings refresh (3600secs) the subscriptions disappeared. After a reboot it works again for 3600 seconds…
In SIP Log we can see an unsubscribe event and don’t know, why this is happening.
