After months of working super reliably, an IAX trunk is now behaving most oddly. It’s a trunk between two FreePBX servers that uses ZeroTier.
Now when I call home from work from one of the Digium D50s there, the phone at home (which is a POTs telephone connected via an ATA) rings but if you answer it it keeps on ringing. Occasionally if you answer it, I can hear my wife, but she can’t hear me. Mostly, though, it just rings and doesn’t stop ringing when you lift the handset.
HOWEVER, internal calls within the home to that POTS connected to that ATA behave perfectly normally.
STRANGER STILL, calls I make from my mobile using a DISA to that POTS phone connected to the ATA work normally.
Even WEIRDER, calls I make from a softphone on my laptop when I’m connected to the WORK FreePBX instance using ZeroTier which then do a 180 and call HOME (so essentially I’m calling home from home but via work) ALSO work totally normally.
Wanna seem my logs?! I don’t know what I’m looking for.
Many thanks if anyone can be bothered…just really strange why this would start happening out of the blue. It sucks! I’m in trouble with SWMBO
