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 : PJSIP syntax

It seems that the comma in the <To: > tag is the origin of this behavior.

Is this an Asterisk problem or a Gigaset one ?
