[Spce-user] Network Configuration

I think I might  have resolved the issue to run media-proxy on multiple 
interfaces on the same machine.
Once I can confirm this is working will I elaborate on how I achieved this.

I'm facing a problem though and it is as follows:

I'm registered via SIP Client on my Internal Network 
0839999989 at 192.168.0.250.

One of the Carriers is registered to fake subscriber 
0839999999 at 10.222.0.250 with Alias 44113001417.

I've made 100% sure that my re-write rule is set on both the subscribers.

I make call to 0044113001417 , but call fail with " No PSTN gateways 
available " in the proxy log.

I'm also not 100% sure why it is not calling to the local hosted domain 
10.222.0.250?

The LB is listening on 10.222.0.250:6090.

Attached the output of the call within the proxy log.


Thanks again for any assistance.

Kind Regards
Deon
