Hi Mark,
since you need to change only the display name, you may use the
uac_replace_from() function (see
http://openser.org/docs/modules/1.1.x/uac.html#AEN160), like:
uac_replace_from("batman","");
this will have no implication on the dialog - no need to do the same
change on the sequential requests.
and yes...probably you need to do this for each initial requests going
to the PSTN GW.
regards,
bogdan

I just debugged the following:
A PSTN gateway we use is completely non-responsive when
the INVITE has this:
From: Mark Kent (desk) <sip:markkent@sip.example.com>;tag=foo
Contact: Mark Kent (desk) <sip:markkent@192.0.2.216:5060>
but things work OK for this:
From: "Mark Kent (desk)" <sip:markkent@sip.example.com>;tag=foo
Contact: "Mark Kent (desk)" <sip:markkent@192.0.2.216:5060>
and also for this:
From: Mark Kent <sip:markkent@sip.example.com>;tag=foo
Contact: Mark Kent <sip:markkent@192.0.2.216:5060>
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:MarkKent@sip.example.com>;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,
-mark
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.
