Any way to assign a dial rule to call a Sip address (not supported by Sipbroker)??

[Jeannie]

Need help on how to create a dial rule, to make Voxalot call a specific Sip address, to be used within Liberailvoip callback settings.

The problems:
1. That Sip network is not supported by Sipbroker.
2. I cannot use the Voxalot 'speed-dial' feature for that, since LIV doesn't allow predefined callback numbers to include asterisks '*'

I know I can easily bypass that by adding another service into the mix (like MSS) - but the whole point is that it must be directly called from Voxalot, for a sensitive test I'm trying to run (must avoid extra latency/transcoding)

Any idea?
Thank you
