Inbound Number Translation

[ianwarb]

Hi Guys

I need some help configuraing a solution for my customer that I don't eactly know how to implement. I am installing Call Manager v.8 for them and as part of this, the wish to do some inbound number translation wihich I will do my best to describe. Each endpoint will have a four digit extension say 1234. the number the wish to present to the outside world is a non-geo number say 0845 111234. For inbound calls they want to following:

External call rings and endpoint (0845111234). This gets translated within the carrier to a geo number say 0207 222 5678 which gets delivered to Call manager. The customer wants this number to be translated to the original 0845 number however the two numbers do not corelate so it needs to be a one-to-one translation which cannot use wild cards i.e. 0207 222 5678 => 1234 (users DN). For outbound calls the users DN (1234) needs simply needs expanding to the 0845 number (i.e. 0845 111234). The customer is connecting to the PSTN using SIP trunks via a CUBE. Could anyone sugest the best way to achieve this

thanks

To recap the Carrier will send you 0207 222 5678 or maybe 25678 or 5678 ? and you want to translation it to 1234 which is the DN of a user. Why can`t you just use a translation pattern?

Create a Partition called "Free Phone number" or anything you want and assign that to the CSS of the GW. Then create a translation Pattern to match the incoming digits from the exchange  5678, 25678 etc and assign the new partition to it- "Free phone number". Within the translation pattern , translate 5678 to the number number 1234- make sure the CSS of the translation can see the DN 1234. Obviously if you have lots of the 0845 then you need to do 1 to 1 translations unless you configure your DN`s to match the digits

yes, in essence the number translations will as follows:

0845 221234 - translated in carrier - 0207 224444 - translated on CCM - 5678 (DN on Phone)

0845 221235 - translated in carrier - 0207 225555 - translated on CCM - 5679 (DN on Phone)

do you think TP's are the most effective way of implementing this. I will try creating the COS structure and test it, the only problem is I have 200+ of these to get through but there is no correlation between the bulk numbers.

thanks for your reply

Why do you have to do the translations in the first place?

Are the calls delivered to single users per 0845 number? Why not keep the number 25678, 5678 if they are unique and then create an extra DN on each phone for the 25678, 5678 numbers. Or you could create a single Translation Pattern export it via BAT and then import the remaining one using BAT using the tempate you exported- I think I seen this mentioned before as do able. Or create the Translations on the actual GW using a text file ?

the reasoning behind this is due to the customer wants to retain the 0845 (non-geo) number on their phones but they have to go through a number translation at the provider so they are being delivered to CCM as geo numbers.

The will be delivered to users as an 0207 number however no part of the number translation is common so i cannot use wildcards. I was looking at  doing this on the gateway however using tranaslation rules, but I can only have 15 rules under the profile, is there another way?

Many thanks for your ideas
