Hello,
For my mobile communication I use a CO trunk. This works well but i need to send a code(#31#) before the number that i want to call because i don't want to send my number to the GSM network. I want to do that automatically.
Is it for all dialed numbers or only specific dialed numbers? If it is for specific ones, you can build a route for that paticular number ot insert the digits in the ars route. How this is done depends on you switch version. Further detail would help.
