You can use variables with the ~r special character in the route-to number command to activate Network Call Redirection (NCR). The digits following the invocation character are the Service Provider network redirect to phone number address without inclusion of an internal access code. Use the any of the following formats:
~r<number up to 14 digits> - This option allows you to enter a specific number. For example, ~r13035552345. This format can contain only up to 14 digits for the redirection address because ~r takes up 2 digit spaces of the 16-digit number field.
~r[A-Z or AA-ZZ] - This option allows you to enter a vector variable as the redirect to address. For example, ~rA. The variable can have a value up to 16 digits during processing since it is not counted towards the number field 16 digit limit during administration. The variable letter(s) can have preceding digits following the ~r. For example ~r123AB. The variable character(s) always count as two digits towards the 16 digit number field limit.
~r[V1-V9] - This option allows you to enter a VDN variable. For example ~rV1. This variable can also have a value up to 16 digits and can have preceding digits following the ~r. The variable always counts as two digits towards the 16 digit number field limit.
~r+<number up to 12 digits> - This option allows you to enter a specific number for the special case where a network Service Provider requires the + character to indicate E.164 numbering for NCR invocation over a SIP trunking interface with the network. For example, ~r+305558754. This format can contain only up to 10 digits for the redirection address because ~r and + both take up 2 digit spaces each for a total of 4 spaces of the 16-digit number field.
~r+[A-Z or AA-ZZ] - This option allows you to enter a vector variable as the E.164 numbered redirection address. For example, ~r+A. The variable can have a value up to 16 digits during processing since it is not counted towards the number field 16 digit limit during administration. The variable letter(s) can have preceding digits following the ~r+. For example ~r+123AB. The variable character(s) always count as two digits towards the 16 digit number field limit.
~r+[V1-V9] - This option allows you to enter a VDN variable as the E.164 numbered redirection address. For example ~r+V1. This variable can also have a value up to 16 digits and can have preceding digits following the ~r+. The variable always counts as two digits towards the 16 digit number field limit.
