I read the the first line without the word "this" almost fell backwards off my chair..... I have looked into this also, the second sip server you need to ensure that no auth is done, but then this means you need to be able to trust what is coming from the first ser, which can be done in terms of IP, but then this can be spoofed. What would be nice is to have SER itself authenticate, i.e instead of each call being authenticaterd, autheticate the entire box, and then possibly have a open connection between the two, which if no traffic passes for sometime is dropped, and then re-intiated when next call comes in.

There is a function, uac_auth, in the uac module which can be used to authenticate a challenge from another SIP server. Unfortunately it has the following problems:

1. Does not handle increment of the cseq. At least in my experience this causes authentication failure, you may have better luck. 2. Missing quotes in the auth header sent by the other server causes parse errors. 3. Digest comparison is case sensitive (DIGEST in auth header causes parse error).

2 and 3 are easy to fix but 1 is a major problem for SER as there is no dialog state kept between requests.

Hi,

I was wondering how I can route my SER users to other SIP servers, without need of authentication to other server.

I mean this:

My User -> Auth -> My SER

My SER -> Auth -> Other SIP Server

My User --------make call--------> My SER --------route call-------> Other SIP Server

Thank you.

Kaveh

read "I've just been playing with this myself." without the word "this" :-) My peering with alot is based on IP, but it would be nice if we could do what asterisk does, and allow a user/pass auth method, so you could just buy sip accounts from providers, and route to each account based upon prefix.

I have looked into this also, the second sip server you need to ensure that no auth is done, but then this means you need to be able to trust what is coming from the first ser, which can be done in terms of IP, but then this can be spoofed.

But if you are peering with an ITSP that does requires authentication its a problem. Some do some dont.

proxy-proxy SSL using stunnel + X.509 certs works great for this if you own both proxies.
