Also,
Please do not copy your entire config to these forums as they are long enough without everyone having to read through your config.
Again, as stated, check out the docs on quintum’s web site because in the pstntg area you definitely do not have the correct settings for answer and disconnect supervision. I would try setting signaling to just loop start, supervision to 3 (both answer and disconnect) and answer delay to 120.
