hmmm - so it’s not JUST IAX, it seems.
It worked well for a week or so and I thought I’d cracked the problem by resetting all the ATAs.
Anyway out of the blue, problems again. I rang home from work over the IAX trunk and the POTs phone connected to the ATA (and then FreePBX) wouldn’t answer the call. At my end I just heard constant ringing tone.
Next I tried calling in from my mobile phone DISA inbound route. This time the call could be answered and I could hear my wife but she couldn’t hear me.
Is this more likely to be the ATA’s fault than FreePBX?
I have the two traces here:
Call wouldn’t answer at all
I couldn’t be heard but I could hear my wife
Suffice to say it seems to be JUST this one phone in the house that gives problems. But it’s the second line on an ATA that works fine for the other line. Is there any chance a dodgy wiring connection could give these symptoms? It seems unlikely to me.
