[asterisk-users] Outbound routing

[Asterisk]

Dear All,

I have a small call center in which I have to define least cost routing for outbound calls. For now I have always done this by routing numbers to different providers according to the number prefix.

However, a new law became effective now which allows people to switch between providers without changing their telephone numbers. This makes least cost routing based on number prefixes much less effective.

Are there any known solutions for this?

Thanks in advance,
Alex
