PJSIP syntax error exception when parsing

My PJSUA2 example is returning the following:

11:31:41.606 sip_transport.  Error processing 575 bytes packet from UDP 0.0.0.0:5060 : PJSIP syntax error exception when parsing 'To' header on line 5 col 38:

and I'm already out of ideas.

Asterisk does register the client, but two seconds later it retuns:

[Jul  2 10:35:16] NOTICE[29444]: chan_sip.c:29614 sip_poke_noanswer: Peer 'cli_id' is now UNREACHABLE!  Last qualify: 0

The " PJSIP syntax error exception when parsing 'To' header on line 5 col 38 " seems to be in the compiled lib, so I don't know how to debug that, and pretty much no idea of what to do next.

Any suggestions at all are welcome.

Line To: <sip:cli_id@192.168.25.7:6000>;ob> present in OPTIONS that asterisk is sending is obviously not valid. You can try to disable qualify in asterisk configuration to disable these OPTIONS messages.

Using 0.0.0.0 IP address is at least unusual and can also trigger problems.
