Hi support:

I have quite a strange problem with our telephone system: From our Snom D315 I can not call a certain number. I wanted to book a Hotel in Brussels calling +32 2 486 63 88 and thus dialing 003224866388. The phone does not do any dialing (for like two seconds) and then says "Connected" and the call time is running but I do not hear anything (there should be a answering machine with instructions). After approx. 1 minute the call ends without me doing anything. I tried this with two Snom D315 and same behavior with both. Strangely, I did the same with two different M25 that we have here and there it works fine. Firmware of the Snom D315 just updated to 10.1.101.11 - but the problem remained. Any idea what is going on here?

Thanks!
