question about voip E.164 telephone no. format

[admin_2]

under command:

dial-peer voice xx voip

destination-pattern [E.164 telephone no]

I need to define a string that can ignore first 7 digits and compare the following digits

i had try "destination-pattern .......20"

but this format is invalid,

how can i config it?

Destination-pattern is matched from left to right.

NUmbers come before wildcards and hence you cannot use this

method.

you can creat a detination pattern "408525512." . This will

match any number 4085255120----9.
