I am having a problem with a PRI in Berlin, Germany.
People can ring from mobiles fine but when they ring from German landlines it fails.
So lets say the main number is 220 83720
The DDIs are 220 83720 01 - 99
Its a bit weird but basically the PRI is 8 digits and the extensions are 10 digits.
The main number works, but when you dialled a DDI say ending in 10, we were seeing 220 83721.
Now whats a bit wacky - it all works grand from a mobile, its only German landlines...
Now I configured
and I have enabled the 'Overlap receiving flag for PRI' in the service parameters.
Any ideas ??? Apparently its related to enbloc and overlap dialling.
Anyhelp greatly appreciated ..
FYI : The Telco have said
They found out that it always works when using Blockwahl and that it never works when using Einzelwahl. If you dial the number including the extension in one block (which is the case when you have the number registered on your phone (either Festnetz or mobile) then you always get through directly to the member of staff. If however you pick up the receiver and dial each number individually (Einzelwahl) then the call is interrupted after 030/220721- when dialing the next digit.
The cisco engineers have to configure the phone system in such a way that you can use Einzelwahl i.e. the system waits until all the digits are dialled/until the dialling is complete.
Deutsche Telekom cannot switch all incoming calls to enblock dialling because this is technically not possible.
Mr XXXX said something about this problem ocurring often with Cisco IP. Apparently Cisco IP is sometimes using a U.S. standard with certain timer settings that don't match with the German Telekom system. He said it would be best to ask the technicians at Cisco. They should be familiar with this problem and might know a solution.
