I found an issue  <http://track.sipfoundry.org/browse/XX-6045> 
http://track.sipfoundry.org/browse/XX-6045, that looks to deal with exactly my 
problem.
And it is marked fixed. In 4.2.

The description of the "Strip User Parameters" check box in the registrar 
configuration is
 
Remove all semicolon-delimited parameters from the userpart of local SIP 
addresses. For example, convert 'sip:user;[email protected]' to 
'sip:[email protected]' when the local domain is 'example.com'.

that is this checkbox is intended to do exactly what i need - remove 
";phone-context=cdp.udp" from the request uri.
(Or may be more precisely would be: registrar will disregard this string).
 
So... is this checkbox known to work in 4.2.1? In 4.2.0? in 4.4.0?
 
Are there any users that use sipx with SC1000?
 
Any ideas how to solve the problem would be greatly appreciated.
 
Thanks and regards,
Nikolay.

Hi all,
 
i have a problem interconnecting sipx (4.2.1 and 4.4.0) to cs1000 (version 
7.00.20).
The problem is that CS1000  sends invite in the following form:
INVITE sip:4002;phone-context=cdp.udp@"mydomain":5080;maddr=<ip 
addr>;transport=tcp;user=phone;x-nt-redirect=redirect-server SIP/2.0
and finally sipxregistrar answers "not found".
As far as i understand the problem is in the ";phone-context=cdp.udp" string of 
the sip uri. 
 
In the maillist archive i found some discussions about that... sipx guru's said 
that the problem was on the cs1000 side.
 
I found the checkbox "Strip User Parameters" in the registrar configuration. 
checked it. Nothing changed.
I tried to route calls through sipxbridge and directly to sipxproxy. With the 
same result - "Not found".
 
So can anybody please shed some light on the following:
1. Is it possible to solve the problem on the sipx side?
2. May be some special configuration is required on the CS1000 side? Can 
anybody please advise what to do?
 
I'm ready to provide any additional info if needed.
 
Thanks in advance,
Nikolay.
