Outgoing calls don't work

[mschmarck]

Good $TZ!

I'm having problems making outgoing calls using a Siemens Gigaset C450IP - or rather, listening to outgoing calls. When I call 00498001507090 (German free call, Die Bahn Automated Auskunft), I just hear nothing at all. As you can see from my dial plan further down, calls to 0049x are routed over Home: dus.net GmbH - VoIP : DSL : Equipment Housing. In the dus.net user control panel, I DO see that the call actually was established just fine:

[code="dus.net Kundenbereich"]
2008-07-24 20:26:22 "Fam S" <038722abcd> 038722abcd 00498001507090 00038722abcd 00:16 00:11 0,000 Germany FreeCall Nummer
[/code]

I also tried calling 0049640390503760 (Alternate B2B contact phone) and in dus.net, I see:

2008-07-24 20:43:11	"Fam S" <038722abcd>	038722abcd	0049640390503760	00038722abcd	00:30	00:21	0,522	Germany Festnetz

(You might also want to check the attached screenshot, it might be a bit clearer about what the numbers mean.)

When you call that number after 6pm German time, you'll get an automatted answer telling you, that you're too late. But as you can see from the excerpts above, a call indeed WAS established (eg. to the 004964... number, I "talked" for 21seconds and I was chared 0,522€).

Same problem with the automatted WDR2 Stau Info (+49-2211-6803050).

BUT: When I call my Swiss mobile phone and change the dial plan so, that it routes the call over dus.net as well (instead of the default sipcall.ch), I hear no ringtone, but after picking up the call on my mobile phone, I can hear myself just fine on both phones. So it sometimes does work, it seems. I'm sure that dus.net was used to reach my mobile phone because of the phone number which is displayed in the display of my mobile (when I set it to sipcall.ch, a different number is shown).

Calls to the echo test *600 and *500 voice mail works just fine.

Can you dial 500 (Voicemail) or 600 (Echotest)?

No go - just silence.

Incoming calls work just fine (either direct via the numbers of sipcall.ch & dus.net and also via SipBroker PSTN gateway (tried many in different countries)). SIPBroker - EziDial also works.

I have the same problems when I change my dial plan to always use sipcall.ch.

Well, I'm out of ideas Am I doing something wrong? What can I do, to make my setup work?
