Alcatel Unleashed

hi all,
i have a customer with 1 IP trunk group with 3 different providers (different ip addresses).
the external call prefix should be ars prefix e.g. 9.

when the user calls 90044xxxxxxxx the call should go to provider 1
90045xxxxxxxx to provider 2
90046xxxxxxxx to provider 3

how can i do this with ars prefix without the use of speed dialling.

thanks

IP - H323? Without gate keeper?
I think you need to use SD.
SD1 90044 (IP)
SD2 90045 (IP)
SD3 90046 (IP)

Manage in SD1 90045 as "overflow SD number", in SD2 90046 as "overflow SD number"

or SIP?

thamks for your reply. its ip-h323.
i have the configuration with the SD, i just wanted to know if there was a "better" configuration.

thanks again
