I've tried googling this but I am having trouble finding the answer.
I want to add **275* to all 800, 866, 877, 888 numbers automatically. So if I were to dial 18005551212, it would send the VoIP provider **275*18005551212. This sends it through an alternative route I've found more reliable with DTMF tones. Can I accomplish this in the digit map?
Currently it is:
(1xxxxxxxxxx|<1>[2-9]xxxxxxxxx|011xx.|xx.|(Mipd)|[^*#]@@.)
Thanks!
