32 seconds Disconnect Problem

i encountred the 32 seconds call drop. i have tried many of solutions of the site and have not worked yet.
these are the logs of:
asterisk -rvvvvv
pjsip set logger on
the page doesn’t admit all the logs what part of them should i’ve to upload first?

Paste the logs at pastebin.com and post the link here.

If possible, take the data from the Asterisk log (the relevant section of /var/log/asterisk/full ), not the console output.

Report whether the problem affects incoming calls, outgoing calls, or both.
