I just debugged the following:
A PSTN gateway we use is completely non-responsive when
the INVITE has this:
From: Mark Kent (desk) <sip:[EMAIL PROTECTED]>;tag=foo
Contact: Mark Kent (desk) <sip:[EMAIL PROTECTED]:5060>
but things work OK for this:
From: "Mark Kent (desk)" <sip:[EMAIL PROTECTED]>;tag=foo
Contact: "Mark Kent (desk)" <sip:[EMAIL PROTECTED]:5060>
and also for this:
From: Mark Kent <sip:[EMAIL PROTECTED]>;tag=foo
Contact: Mark Kent <sip:[EMAIL PROTECTED]:5060>
Now, I know that the EndUser box should put quotes in there to be
safe. RFC3261 says "special characters MUST be in a quoted string to
be used within a parameter value."
But that's not the point of this post... the point is,
should I be rewriting every header? Is that standard practice?
BTW, I have the same hangup with the SJphone softphone,
but there I think it's because of this:
From: "Mark Kent(mac)"<sip:[EMAIL PROTECTED]>;tag=foo
See, no space between the double-quote and the left-angle-bracket.
So, should I be re-writing headers to present a single face,
independent of the EndUser boxes, to external SIP gateways?
Thanks,

P.S. FYI, the box that is not putting in the quotes is a SPA3000
running 3.1.10(GWd). A SPA942 running 4.1.10(e) puts in the quotes.
