[EMEA ISDN ERA DIAL-PLAN FOR MUNICH GERMANY ASSISTANCE REQUIRED]

Greetings – I am seeking input on developing a dial plan for a site that has been thrown my way in Munich Germany.  I’m new to ISDN ERA and have been using NANP for years.  Any input regarding developing a dial plan for Munich Germany, including sample configurations of CUCM and Gateways, would be greatly appreciated or if you can point me to resources ( in the right direction) would be immensely appreciated.  Thank you.

 

  • The german dial-plan is completely variable, which means you cannot tell UCM how many digits he needs to collect. Instead of a 9 for an outside line they use 0. Further a long distance call is not 91 it is 00. Internationial is 000 instead of 9011. You see that they just pile up 0s the farther you go. The easiest route-pattern is simply 0.! (assuming UCM) but this would incur interdigit timeout. To avoid waiting for an interdigit timeout, you need to specify "overlap sending" on the gateway so all digits are pulsed out as you continue dialing. The PSTN knows when it will be happy with the amount of digits and connect the call. If you like more granularity (COS for different users) you may configure more different route-patterns like 0.0! for long distance and 0.00! for international calls.

     

    Just a very short intro in variable dial-plans.

     

    Best
