Hi Currently I am using lcr to choose my gateway based upon prefix, now I wanted to choose a gateway based on username. I was thinking that if a user made a call to say 001xyz I could detect its username, see if in usr_prefences (using avp) it had a variable set eg:add_prefix, if so add a prefix of 2 to the number. Then in lcr add a false prefix of 2001 to the table with the new gateway, and at the gateway remove the prefix, before making the call, this way I dont have to ask users to dial any special prefixes. Any better ideas Iqbal
