If the time isn’t exactly 32 seconds, one would have to guess without detailed logging, and even with an exact 32 seconds, one really needs the logs. As I haven’t heard of this API before, I don’t know whether this is just SIP to Asterisk, in which case one wants the “pjsip set logger on” output (or equivalent legacy driver output) from the Asterisk full log, plus the other verbose level 5 output.
