audio)<BR><BR></FONT></DIV>
<DIV>Hi,</DIV>
<DIV> </DIV>
<DIV>We are also having a problem with X-Pro and X-lite build 1088
when registering to a SIP proxy based on libosip. The X-Pro is not using the
double-quotes on the nonce value of the Authorization header, which is causing
an error on our proxy when parsing of this header (Libosip requires the double
quotes).</DIV>
<DIV>I have sent this question to the Xten support forum but they said that
the double quotes are not mandatory, though libosip requires them.</DIV>
<DIV> </DIV>
<DIV>Any thoughts on what is the correct behaviour of the double-quotes
on the authorization header?</DIV>
<DIV> </DIV>
<DIV>Thanks,</DIV>
<DIV>Chuck</DIV>

Re: Xten-RTPProxy choppy audio<BR>> <BR>> <BR>> Ok, I see, probably
it tries to send a RTCP packet, which is OK by <BR>> itself, but handles
