[Freeswitch-users] Routing DIDs to Dynamically Registered SIP User

[David Ponzone]

I really don't think it is as:
1/ i was not able to find a parameter to alter the INVITE URI
2/ FS itself has a parameter to change the behaviour and use the SIP  
To instead of the INVITE URI as the destination_number, so it would  
tend to prove that it's the other party's job to use the right field.

David (Allen, I am not talking to myself :) ), can you give us some  
examples of PBXs who rely only on the INVITE URI ?
Are you sure they don't have a parameter to change that ?
