We are in the process of rolling out call manager 6 cluster in Europe. Currently We have call manager 5 Cluster in NA.
1) Inherited the system. ( It has 4 digit dial plan which will be starting to overlap soon)
2) We have inter cluster trunk setup ( no gate keeper)
3) VOIP will be deployed in France, UK, Romania, Germany Sweden and more….
a) since these countries use different dial plans ( Dial different length of digits , Emergency services etc…
b) Possible integration into a Avaya and CME deployment)
What is the best dial plan for this situation?
Currently the Consultant has recommended 5 digit dial plan?
1) What about site codes? for each country or office location?
How do get out of this mess…. I scoured the net and found no real world examples. I have ready the SRND but I am still lost. I have searched the Cisco net forms also.
Many Thanks in advance.
