Answer to: original receiver number after forwarding

answer to: viewtopic.php?f=1&t=88541
@david55:
Yes, exactly, diversion header is supported by asterisk.

The problem is that the provider that I’m using don’t send that header after forwarding.
Do you know any provider that send this header and provide a DID incoming number?

I’m contacting a lot of providers and they don’t send that header. Why?

Thanks in advance david55, again.

No market demand? (At the moment, I can’t think of a commercial reason, but ITSP’s will also not supply services that lose them money.)
