Loop Detected, Request is sent back to same UAS

[karthikmscss]

1. Brekeke Product Name and version:
Brekeke SIP Server , Version 2.0.7.2 Personal
2. Java version:
1.6.0_01
3. OS type and the version:
Windows XP 5.1
4. UA (phone), gateway or other hardware/software involved:
X-Lite, OPENSER as a Registrar
5. Select your network pattern from http://www.brekeke-sip.com/bbs/network/ ... terns.html :
My Setup is not available in this link
6. Your problem:
ONDO is giving Loop Detected

Settings

UA1 - X-Lite
Outbound Proxy - ONDO
Registrar - OPENSER

UA2 - X-Lite
Outbound Proxy - ONDO (Same What UA1 uses)
Registrar - OPENSER (Same What UA1 uses)

UA1 making call to UA2, the expected flow will be

UA1 -> ONDO -> OPENSER -> ONDO -> UA2

[When Registering ONDO will modify the contact and send it to OPENSER, so OPENSER will have address of ONDO]

But the actual flow is
UA1 -> ONDO -> OPENSER -> ONDO -> OPENSER (this is wrong) -> ONDO -> OPENSER -> ONDO , now ONDO generating 482 and ACK is sent by OPENSER , then ONDO finding address of UA2 and sends the INVITE (this must be done before itself)

Will you please help me what's wrong in this setup, is there any way to configure the ondo as a proxy server(it should not modify Contact before forwarding)?

In this setup the Bye from either endpoints are dropped at ONDO SIP Server and the same setup is working fine when Asterisk PBX as a Registrar instead of OPENSER.



Thanks in Advance,
