asterisk users - Nov 2007 - Registration problem: UA -> SER -> Asterisk

Hi,

 

we a have a SER (OpenSER) in front of 2 real-time Asterisk.

SER simply forward SIP messages to 1 of the Asterisks:

UA --> SER --> Asterisk

We have a problem with REGISTERs:

Asterisk answers with 200 OK, but changes the Contact header, inserting
the IP of SER instead of the original IP (the IP of the UA).

It seems that performs a sort of NAT-traversal, but all the elements are
on public IPs!

 

The Asterisk's version is 1.2.21, they are in real-time configuration,
installed on a virtual machine with gentoo-linux.

 

I've tried the same scenario with an Asterisk 1.0.9 (without virtual and
without real-time) on a Fedora Core distribution, and it works.

 

Any idea?

 

Best regards,

-Stefano

Stefano,
It is not Asterisk, It is SER (dispatcher module ?).
Why Asterisk is acting as Register ? make sense use openSER as
Register/Proxy and Asterisk only Proxy and MG

Hi,
 
Yes it make sense to have multiple registrars and to have SER acting as
a transparent proxy that forwards also REGISTER messages.
 
The question is: why it does not work! :-(

Stefano,
if you have distributed Registrars, which will keep the user location
of registration ?
And you do not need OpenSER to fwd Register message.. Register / Proxy
/ Redirect could be totally separate entities.

By the way, if you post the SIP Register message likely someone could help you.
"Check in Register msg Contact field"
Contact: Bob <sip:6000@ 69.177.27.32>;expires=660.

Probably SER replace it.

Beside it, you can have a multiple OpenSER and Radius (AA) with shared
db acting as Registrars, I do not understand why you want asterisk to
do that.

Regards,
Giovanni
