This error is caused by the phone sending an erroneous sip header not
by asterisk pjsip stack. solution would be to change the phone.

hello,

you receive this error because the second line of SIP message not can
begin without a Header. You Phone or server (maybe OpenSIPs or Kamailio)
whet quitting a Via Header make some kind of error so the result is you
have the Via Header in two lines instead one.

Regards
