[Serusers] Proper handling of REFER

[Klaus Darilion]

Take a look the Refer-To header. This will be evaluated by the other 
party. If the other party is a gateway it must have route for the 
destination. This is often a problem if the users use a different dial 
plan than the gateways (e.g. user dial 00431... and the gateway uses 431...)

If this is the problem you can use textops to rewrite the Refer-To header.

Further you should also screen the Refer-By header for bad destinations 
- e.g. 0900 number ... because must phones accept a REFER without asking 
the user (permissions module)
