problems with status 302

estenet · Post by **estenet** » Fri Mar 16, 2007 8:10 am

1. Brekeke Product Name and version:
Brekeke PBX, Version 2.0.7.0 , Pro
Brekeke SIP Server 2.0.7.0/217

2. Java version:
java-ver 1.5.0_11

3. OS type and the version:
Windows 2003 server

4. UA (phone), gateway or other hardware/software involved:
any UA, redirect server on other end

5. Select your network pattern from http://www.brekeke-sip.com/bbs/network/ ... terns.html :
Pattern 4

6. Your problem:
UA gets a 404 after sip/pbx receives a status 302.

Dear support,
We need to establish a phone session with a server which is on a different Lan.
Sip/pbx is on a public server.
UA is on our private lan.
if on the other hand we have a "normal" UA, there are no problems.
Problem arise when the other end wants us to contact a "redirect server" which should dispatch us to the appropriate end.
this redirection comes in form of a status 302 message.
What we can see is that pbx receives the 302 message, it answers with ack then sends a 404 to the ua.
From what i read on this forum it should have created a new invite to the new destination (contact field on the 302 message).

Am i doing something wrong ?
Thank you in advance for answering.

i've colored in red numbers and ip.
Redirect server should redirect me to another end... this is made by changing port (in this example).

If you call to the sip uri "sip:*dest_number*@*dest_redirect_server_ip*:19000",
can you reach the destination ?

My pbx could handle 30x.
