ESP32 SIP registration problem - Qualify-Asterisk related

[Patsjemoe]

When using a softphone on my PC, registration to Asterisk (on my laptop) registration works fine.
(also calls work).
When using ESP32, it registers but says Unreachable when I have put Qualify=yes in Asterisk.
When I change qualify to no, reload asterisk, exit, then change again qualify=yes and reload asterisk, then my ESP32 shows OK/ms, and can call android/linphone. (only voice if I call from the phone to esp32, not from esp32 to linphone...but that is the next problem to solve).
Could this be a bug in ESP32-VOIP SW ? Or how can I get around this problem ?
