How to configure a backup provider in dial plan in case the call fails?
 

Hi,
I am doing some test with voxalot and sipsorcery.
In Sipsorcery dial plan there is a command that allows using a secondary SIP provider, if a call is failed with the primary provider. This is useful if I have a residual credit with an old provider and I have already bought credit with a new provider. I can use till the last cent the old provider, and when the credit is finished the dial plan uses automatically the new one, without any call failure and without need of changing immediately the dial plan.

The command is this:
sys.Dial("oldprovider[fu=+39xxxxxxx]&newprovider[fu=+39xxxxxxx][dt=5]")

Is there a way to do this with dial pattern string of voxalot?
Thanks in advance!
Alberto

Automatic failover like in SipSorcery is not possible at the moment...
