problem calling sipbroker alias through voxalot
 

This is my setup.

There is a sipbroker alias *011AAAAAAAA to voxalot account BBBBBB@voxalot.com

I'm calling from another voxalot account to *011AAAAAAAA, call is not getting through.
Call from sipbroker access number or from another VSP to *011AAAAAAAA is OK.

Receiving 2x 100 Trying and finally SIP/2.0 407 Proxy Authentication Required

What's wrong?

Curious why you are you not just dialing *010BBBBBB?

The 407 is warranted when calling Voxalot<->Voxalot to stop spoofing. Even if you are using SIP Broker as an intermediate.
.

The idea is to have different To: fields with the same account.

BBBBBB account is my Asterisk.
When I'm calling from my Nokia (for example) I will see *010BBBBBB on Asterisk and will handle this call according to scenario #1.
When I'm calling from Sipbroker number I will see *011AAAAAAAA on Asterisk and will handle this call according to scenario #2.
In both cases the call will come to the same voxalot 'registration'.

If alias dialing will not work then I will have to register one more voxalot account and forward it permanently to BBBBBB. Please comment. Thanks.
