BLF on Sip Trunk (check extensions status)

Dear all,

i have configured two Asterisk PBXs (named A and B), they are connected via SIP Trunk.

I need to configure on A the BLF in order to see the status of the phones registerd on B.

Is it possble to do this?

Thanks and regards,

I’d look at this:

The support also varies between Asterisk versions. In Asterisk 13 you can use PJSIP itself to exchange this information between systems.

Thank you very much for your help, is there any guide that explains how to configure PJSIP for this feature?


There’s a complete guide including configs[1] on the wiki.
