Callmenu and Callthru: DTMF was not accepted

Hi,

We have had troubles with our digital receptionist and call-thru: the sent number was not accepted via DTMF.

The number was stored in this format in my Nokia E71-1: "xxxxxxxxxxxxxxxp106#

Log:

"2011-02-24 11:25:19 "0179XXXXXXX" <0179XXXXXXXX> s sipga­te.de sipgate.de callthru WaitExten 00:00:11 "

After edting the menu of the receptionist yesterday it was OK till today. Today has it gone wrong with call-thru as well.

I have restarted the system just now. It seems to be OK:

Do you know what the reason can be?

Thank you for controlling the problem.

Regards,

P.
