Deutsche Telekom

Can anyone give a working example for a configuration for using sipdroid and pbxes with a voip number from Deutsche Telekom, please.

Sipdroid connects easily with pbxes, but pbxes seems not to connect to t-online.de. I keep getting only the rest of the error message "... durchgestellt werden. Bitte versuchen Sie es später noch einmal."

RE: Deutsche Telekom

You missed to add "@t-online.de" to your authname. This is described in the German section of our News forum.

However the trunk still does not register. Probably a timeout after unsuccessful attempts.

RE: Deutsche Telekom

Thanks a lot for your reply.

Unfortunately I still can't get it to work. I keep getting »…bitte versuchen Sie es später noch einmal.«

It is all about the SIP trunk username and password, right?
Username: telephone number with local prefix
Password: password:xxx

xxx is the one email address I use for logging in at telekom.de, isn't it? I don't have one that ends with t-online.de. I use one with @web.de. Can this be the problem?

I have tried with and without :…@web.de, with anonymus@t-online.de, with prefix+phonenumber@t-online.de - nothing works.

On my Mac I use the app Telefon by 64 characters. There username is also telephone number with local prefix and password is just the Telekom Internet password without :email !? And there it works. Can anyone explain to me what the difference is? Which password syntax will be right?

RE: Deutsche Telekom

I remember T-Online used to have addresses like customernumber@t-online.de. This number is not your phone number. Do you find anything like that?

To find out why the Mac app works you could create a SIP log there, and post the REGISTER message.

RE: Deutsche Telekom

I have tried any variations with any of the many numbers and login things I do have from Deutsche Telekom. Nothing works.

Entering the standard login data directly in Sipdroid works (as long as I am at home) as well as in the Telefon app on my mac (at home).

The pattern seems to be: It works from home. It works from nowhere else.

Can it be that Deutsche Telekom blocks logging in from places other than where the number has it's home DSL place?

RE: Deutsche Telekom

No, that's not the problem. Other customers register fine.

All of them got xxx@t-online.de authnames. The other solution would be to log a SIP trace from your Mac app.
