Hi,

We upgraded an Asterisk 11 server to 16.1.1, going from chan_sip to pjsip, on a site using Gigaset phones. They are registring well despite the fact that we get a lot of errors like

[Feb 22 18:30:07] ERROR[1556]: pjproject: : sip_transport. Error processing 367 bytes packet from UDP 192.168.1.108:5060 : PJSIP syntax error exception when parsing ‘To’ header on line 4 col 51:

It seems that the comma in the tag is the origin of this behavior.

Is this an Asterisk problem or a Gigaset one ?
