My log is filled with Log filled with this kind of thing:

"[2019-08-31 16:46:16] NOTICE[4855] res_pjsip_exten_state.c: Endpoint '24' state subscription failed: Extension '02233936622' does not exist in context 'from-internal' or has no associated hint

02233936622 is a number in my Digium Phones Phonebook, there are other examples for other external numbers, but “subscribe” is not ‘ticked’ - so am surprised a subscription attempt is being made.

The phone/endpoint will only try to subscribe to something if it’s told to. Which is sounding like someone has a BLF setup for this to just speed dial. BLF causes subscriptions.

What Tom said in more detail:

Pjsip set history on

A bit of background. A BLF button on a phone has an LED, and the LED changes depending on the status of the programmed device. The mechanism by which this is done in Asterisk is called a hint. So the phone does a SIP SUBSCRIBE to a particular hint which tells Asterisk that it wants to track the status. Asterisk in turn will send a SIP NOTIFY whenever the device status changes, and the phone interprets the NOTIFY to make the appropriate LED changes on the button. The error message notification …

Thanks Lorne and Tom. That does sound like it’s the problem. I don’t really know how to make the entries speeddials rather than BLFs.

• I’ve told Freepbx not to bother trying to subscribe
• In the DPMA settings they’re described as rapiddials rather than BLF.

If it’s not a major problem for the system, and doesn’t waste resources, I guess I can just leave things as they are!

Thank you
