Did you make this fax client? or someone else? Generally re-INVITE doesn't have to have authentication headers. but it seems the provider requires authentication with "401 Unauthorized". I did not make the client. The provider requires authentication and told me that there is no way around it, so ...

ioan, If a provider sends an INVITE, I think you don't need any authentication for the FAX client. Is it correct? It seems like the provider send an INVITE and then the client sends and INVITE back: INVITE sip:2027217140@150.12.12.53:5060;transport=udp SIP/2.0 Via: SIP/2.0/UDP 139.24.5.16:5060 ...

Can you paste the FAX client's INVITE packet here?

Sorry, I was wrong, the provider sends the INVITE for receiving, not the client.

Does it mean that a provider sends INVITE packet to the fax client thru Brekeke SIP server?

No, the fax client sends the INVITE.

Do you know which SIP header it is? It it based on SIP's digest authentication? Yes, the Authorization part of the SIP header looks like this: Authorization: Digest username="abc",realm="aaa.bbb.ccc",nonce="xxxx",uri="sip:123@x.x.x.x",response="abc",algorithm=MD5,cnonce="123",qop=auth,nc=00000001

ioan, Does the above log indicate the problem?

6. Your problem:

Is it possible to have a rule that will forward the call to the client "ioan" (To=sip:ioan@) if the client is registered, and if not, send the call to an IP ($target=123.123.123.123) ?

SIP Server , Version 2.0.7.0 Evaluation
Windows 2000
CASFax
Pattern 4

I need to make a rule for the DIDs that end in 52 to go to one IP and everything else to another IP.
Can you please help me with this one?

TIA
