User Unknown Error for incoming call from Gateway

[slickric01]

I've been testing 3CX for a while now and have been able to figure everything out except one remaining problem. We have a PRI terminating on a Cisco 1760V gateway. From there we're going to the 3CX server using SIP. I've created a gateway in 3CX as well as an inbound route, but I'm having a problem getting inbound calls to terminate correctly on the server.

I've created a PSTN device for the g/w and created a port ID and Auth ID of 10002. When an incoming call comes in, I see a 407 proxy auth required going from the 3cx to the g/w. The g/w responds with the auth info that appears correct:

P

roxy-Authorization: Digest username="10002",realm="3CXPhoneSystem",uri="sip:10.1.10.118",response="0a32e3a0a0103a6cdd503adefccb100b",nonce="414d535c01cbf36033:92f692e1ab14e7a7f4309796a63b5ee4",algorithm=MD5

The underlying trace log shows the following lines/error:

12:33:36.713|.\ServerAuthManager.cxx(129)|Trace5|Resip|::ResipLogger:Checking for auth result in realm=3CXPhoneSystem A1=
12:33:36.713|.\ServerAuthManager.cxx(134)|Trace5|Resip|::ResipLogger:[b]User unknown 10002 in 3CXPhoneSystem[/b]
12:33:36.713|.\Helper.cxx(375)|Debug8|Resip|::ResipLogger:Helper::makeResponse(SipReq:  INVITE [email protected]:5060 tid=2AA7EF1 cseq=INVITE [email protected]:5060 / 102 from(wire) [b]code=404 reason=User unknown[/b].
12:33:36.713|.\DialogUsageManager.cxx(866)|Debug8|Resip|::ResipLogger:SEND:

The end result to the g/w is a 404 user unknown.

I have disabled the requires registration for inbound/outbound.

Bottom line, if i have a port id and auth ID of 10002 set up in 3CX why is it returning user unknown??

Thanks for any help.

I think URI should be not

uri="sip:10.1.10.118"

but

uri=sip:[email protected]

or

uri="sip:10002@3CXPhoneSystem

Try to adjust this in your gateway.

Thanks for your help. I've been having a lot of grief with the Cisco gateway and authentication.

Instead of figuring out the compatibility problems, I successfully configured the gateway as a custom VOIP provider and trashed the PSTN device configuration.

As far as I can see there's no disadvantage to me running my gateway as a VOIP provider, right?

Thanks,

I was not able to implement the solution. I believe that I had a limitation of the Cisco IOS running on the router which didn't allow me to set authentication usernames on a line basis.

The workaround I came up with is working well for us, which is using the gateway as a generic SIP provider.
