Hi Support:

Sorry for my continuous posting about registration failure. As u know, if the media engine receives a challenge to a REGISTER request sent to registrar, it should be responding with a new REGISTER with computed authentication credentials.
I have been trying register my own sip account with public deltathree sip server with console based sample DialerTest. But always failure. I am sure that my own authentication credentials for registration is correct and I have modified source code of DialerTest to have my credentials built into it. However after many times of efforts, DialerTest complains as follows:
"Error: Could not enable registrar support. Error code: SipRegisterAuthorizationError".
I have checked reference manual for error info which reminds me AddAuthorizationCredentials() API should be performed prior to EnableSipRegisterServer() is called. In fact DialerTest source code does that per above instruction.
On the other hands, in terms of SIP exchange, when 401 response is received, media engine do not transmit second new register request with computed authentication credentials.

Here is Log:

Hi George,

Normally we don’t handle support issues on Saturday but we were performing other dev work and are just about to complete a solution for you.

Hang on… we have fixed the issue and will repost shortly.

Thanks bud,


Support

Hi George,

You are going to cry when we tell you what the problem was.

When the media engine received the challenge response from your provider, the authentication type specified in the 401 response was all capitol letters “DIGEST”.

When the media engine parsed the SIP 401 response, it had a parse error because the authentication type was not “Digest”. Notice the case difference.

Anyway, we updated the WWW and proxy authentication parsing code in the media engine to handle any authentication type whatever the case. We performed a few tests and all looks OK. We even tried to call our self via the service provider but I guess they don’t route calls back to the same SIP user agent. We are glad you identified this for us. We hope you have not wasted a ton of time on this. Just a simple snafu…

Here is a SIP log using the latest v6 media engine:

We will send you via email a v6 “engineering release” so you can get on with your work. Also note that we added a new API proc called SetUserAgentInfo() that will allow you to set the “User-Agent:” SIP header for all transmitted SIP messages. Hust call this new API proc once after the engine is running and the media engine will handle the rest.

Don’t worry about posting to this forum. As long as its constructive stuff, its all good. :)


Thanks,


Support

Hi George,

Unfortunately we can’t let that source code out. Frankly the C/C++ source code is only used by us developers and is not pretty. Not that the test utility soft phone code is bad – mind you, its just that we use the test app for many test scenarios and we would not want to give customers the impression that the code for the utility soft phone is a typical example of our work. You know what I mean?

Anyway, don’t worry about having that source code. Once you get started on your call dialer app, we support you for up to two months during your development. After that, we suggest customers work with us using a simple support agreement structure.

We will be able to help you and give you more concise info and examples – better that looking at the source code for the utility soft phone.

By the way, not that managed code is bad, but we hope you are going to develop your VOIP app using C/C++ if possible if you are thinking about a high line density deployment.
