FreePBX 17 (PJSIP) BLF not showing with two endpoints registered

[programanything (John Ockelford)]

We’ve upgraded to FreePBX 17 and our configuration has worked except where we have two endpoints registered on an extension, the busy lamps don’t light. (We were using chan_sip before so this is new configuration.) Our Snom D715 deskphones subscribe and show BLF hints, but not for those of us with DECT handsets as well. The deskphone subscribes, but it doesn’t get hints.

Has anyone found a solution to this, or have I missed some configuration setting in PJSIP? I’ve not found any posts relating to this even in the wider asterisk community.

Is there any SIP NOTIFY messages being sent to the phones ? Can you post some logs ?

What is “Max Contacts” set to in the “Advanced” tab of the Extension ?

Does toggling “MWI Subscription Type” to “Unsolicited” help ?

Thank you for your reply. After our site shutdown for electrical work, everything appears to be working properly. I’m now getting the BLFs as expected. I had rebooted freepbx and the phones, so I’ve no idea why it wasn’t working before.

I will keep an eye on it in case there is some weird sequencing issue.
