I’m trying to switch from an onsite FreePBX box to a cloud-hosted PBX, and I can’t get BLF to work with the new setup (they were working fine with our local rasPBX).
All our phones are behind NAT and are connecting to a remote FreePBX 220.127.116.11 server on FreeBSD with Asterisk 1.8.
When I run “core show hints”, the correct status of all the extensions is displayed, but it says “Watchers 0” for each of them - so the phones are apparently not subscribing to the hints.
The phones are Aastra 6757i and are using RFC 3581 to work around the NAT. Calls work fine and the server knows the status of each phone, but it’s not reflected on the phones.
“sip show subscriptions” says “0 active SIP subscriptions”.
What am I missing?
