snoopy,
Welcome to the forum
This will do what you want:
Physical Interfaces -> LINE Port -> DigitMap : (xx.)
Service Providers -> ITSP Profile A -> General -> DigitMap:
(<011852:**8>xx.|1xxxxxxxxxx|<1>[2-9]xxxxxxxxx|<1415>[2-9]xxxxxx|011xx.|(Mipd)|[^*#]@@.'@'@@.)
If the numbers are always 011852 followed by exactly eight digits, then this will speed up dialling a little:
Physical Interfaces -> LINE Port -> DigitMap : (xxxxxxxx)
Service Providers -> ITSP Profile A -> General -> DigitMap:
(<011852:**8>xxxxxxxx|1xxxxxxxxxx|<1>[2-9]xxxxxxxxx|<1415>[2-9]xxxxxx|011xx.|(Mipd)|[^*#]@@.'@'@@.)
