Sincerelly I can't understand the usage/requeriment of "user"
parameter. How would detect a phone if the dialed number is a PSTN
number or an extension? For example:
- 1004 is a short number in Spain (Telefonica)
- 2002 could be a domain user

How

I expect that phones don't need to implement all the PSTN dialplan of
the world :)
