Hi @ all,
i have a problem with call-forward-all and i hope someone can tell me the right way to do it.
Since a few weeks, i could forward with redirect,.
But the portal is switched and that did not work anymore.
In the technical description of the provider i find:
1. Call Forwarding by Deflection (302)
or
2. Call Forwarding by New INVITE
I konw, that i have a prolem with the numbers.
By example:
A calls from external to B
B has set a call-forward-all number (C) for outside
And so a call to C (A -> C)
So, when i now redirect/bridge or transfer, i have callee and caller from outside
and no number of my own account. So the provider reject that.
What is the right way to do such a forward from outside to outside,
so that C sees the calling number from A (and if possible, the skipped nr. from B ?)
I think, the best way would be nr. 1. 302 (only one leg is used)
But what i have to do for that ?
What variables need to be changed (for the caller id that C saw)
How do i build that 302 forward ?
I hope someone can explain that to me.
Thank you.
Best regards,
MrWeb
