CallForwarding using a provider to forward the call
 

Hi all,
anyone knows if it is possible to do the following thing :

I registered two providers in my voxalot account : skypho and freecall.

I would like that incoming calls to skypho (and possibly to freecall) be forwarded to my cell phone using freecall to call my cell phone number.

Technically it should be possible as it is possible to make a "Web Callback" using the same provider (freecall) to call my number and the destination number.

But I tried many expressions in "Call Forwarding" like:
sip:001963254123412@sip.voiparound.com;uid=myuseri d;pwd=mypasswd
with no success.

Anyone knows if it is achievable,
Thanks.
