Thanks Samuel!! I will do more research to find the SIP ALG! Regards, Ricardo.- -----Mensaje original----- De: samuel [mailto:samu60@gmail.com] Enviado el: jueves, 07 de junio de 2007 3:43 Para: Ricardo Martinez CC: serusers(a)iptel.org Asunto: Re: [Serusers] Parse Error : Bad Via? The Via header ends with a semicolon (;) and that's not a valid end of header character. I've seen this problem when there's a SIP ALG in between the UA and SER that removes parameters but does not do it properly. The problem I faced was with rport parameter: the UA added rport to Via header, the router removed the rport BUT it left the semicolon->invalid header!!!! Solutions: 1.- Stop SIP ALG in the router!!!!!!->It will save you further headaches and weird behaviours.... 2.- Configure UA to not use rport parameter. Hope it helps, Samuel 2007/6/6, Ricardo Martinez < rmartinez(a)magenta.cl&gt;gt;: Hello list. I'm getting this error for a REGISTER. REGISTER sip: lidersippy.redvoiss.net SIP/2.0.
