483, 486 and 503 ..

3. OS type and the version: UBUNTU 8.04

6. Your problem:

Hi Everybody:

I'm trying to connect a PBX (Mitel 3300) with the Brekeke Sip Server.
It's OK from X-lite by example to Mitel extension...

but, if I want to make a call from Mitel extension to X-Lite or any other device, I Can't!

This is a Ethereal capture:

200.xxxxxxxx 192.168.2.1 SIP Status: 100 Trying
200.xxxxxxxx 192.168.2.1 IP Fragmented IP protocol (proto=UDP 0x11, off=0)
200.xxxxxxxx 192.168.2.1 IP Fragmented IP protocol (proto=UDP 0x11, off=1480)
200.xxxxxxxx 192.168.2.1 SIP Status: 483 Too Many Hops

This kind of error is random. When the Ethereal don't see this, the 486 and 503 error appear!

any idea?
Thanks a Lot !

who sent such error responses?

192.168.2.1 ---> PBX (Mitel 3300)
200.xxx.xxx.xxx ----> Brekeke Sip Server

When I try to call from Mitel Extension to X-Lite (Registered on Sip Server) the Ethereal show the 486 and 483.

Did X-Lite send 486 response?
Can you find "Server" header in the 436 response packet?
If so, what does the header indicate?
