I am currently having a problem with my CallManager configuration.
We are running Cisco Unified CallManager 4.2 configured for a North American Dialing plan but we are using it as the CallManager for our Munich office in Germany.
We are experiencing problems with the amount of digits that the local Telco is pushing. Sometimes they push 11 and sometimes they push 12. Whenever I created a translation pattern for 11 digits it works, but when a 12th digit comes in the translation patter will only match and work for 11 digits.
Here is an example:
Here is some basic information:
089 7504 090 <~~ Main Number
089 7504 0901 <~~ Main Fax
When the user calls
089 7504 09015
The translation patter will find a match on the 11th digit (1) and will send the local Telco a stop signal.
While reading Cisco Unified Communications SRND (based on CUCM 6.x), I found a mistake or misunderstanding in Cisco document:
"It is possible to use route patterns instead of translation patterns to block calls within the line calling search space
The main difference between using a route pattern and a translation pattern to block calls is the end-user experience when trying to dial a blocked number, as follows:
â¢ When using a translation pattern, the end users will be able to dial the entire number and only then will they hear a fast-busy tone.
â¢ When using a route pattern, the end users will hear a fast-busy tone as soon as the number they are dialing can no longer match any allowed pattern. This behavior assumes an IP phone running SCCP, or an Type-B IP phone running SIP with no SIP dial rules configured in the phone."
Did you find a way around this issue, i will be rolling a gateway out in Munich attached to a UCM cluster in the UK. i noticed the variable length numbers for fax, i thought it was a mis print, is this common in Germany ?
