The "treat long distance prefix as optional" is indeed checked (and the
dialplan has been activated).
That said, I think my core question is, according the applicable SIP
RFCs, is the "To:" field in the INVITE packet of SIP "allowed" to be
different than the argument of the INVITE field?
If they can be different, then I have a gateway issue because it's
clearly using the "To:" field to form its dialstring. If not, then we
have a sipX issue as its only modifying/updating the INVITE argument
(not the "To:" field).
I have verified (via tcpdump/wireshark) that the gateway receives from
sipX a SIP packet of this form (i.e. INVITE line with digit '1'
correctly prepended to dialstring, "To:" field without the digit '1'
prepended to dialstring), so it's apparent what's occurring--I'm seeking
which is deemed correct behavior so I can followup and hopefully get it
resolved.
Thx/all thoughts welcomed-

Good question.
I don't think your issue is a gateway issue, rather go to your
dialplan in questyion, click ADVANCED and see if the
option:
Treat long distance prefix as optional
is checked, if not CHECK IT, apply, activate, try. Perhaps leave
your proxy log set to debug and tail the log file with:
tail /var/log/sipxpbx/sipXproxy.log -f
Post your results.

In my long distance dial plan, I have sipX (v3.10) prepend the
necessary
1 for dialing outbound long distance calls over the PSTN. Using
a
network sniff, I have verified that sipX does indeed do this and
creates/sends the following INVITE to the gateway:
INVITE sip:[EMAIL PROTECTED] SIP/2.0
Record-Route:
<sip:172.20.1.101:5060;lr;sipXecs-rs=%2Afrom%7EYmIxY2ZiMjA%60.400_authru
les%2Aauth%7E%21eae23d5a72f9f0d65973ce6895b2cf13>
Max-Forwards: 18
Contact: <sip:[EMAIL PROTECTED]:25948>
To: "9495551212"<sip:[EMAIL PROTECTED]>
From: "Garage"<sip:[EMAIL PROTECTED]>;tag=bb1cfb20
Call-Id: MDVlNDM1NmU3ODE5ZmI0NjhmNGQzMzdiODJmNzg2ZDQ.
Cseq: 2 INVITE
...
However, the gateway (with no other dialstring-altering dialplan
of its
own) stubbornly dials the number in the "To:" field--not the
target in
the INVITE line of the packet. This call then fails in the PSTN
since
it's missing the leading digit '1'.
Am I correct in assuming this is the gateway's problem--and not
one
where sipX should be altering the "To:" field of the INVITE?
Any info/help is appreciated/
