Register without pre-registration in a csv file.

[Hector-Mina-98]

According to the examples, it seems I need to create a CSV file with the users' information. But I would lilke to register any user of my PBX without having to add them to a file first and just by using the command. Something like this:

sipp -sf /usr/local/src/register.xml -set username 1000 -set authuser 1000 -set remote_host 192.168.0.3 -set secret mysecret123 -i 192.168.0.2 -p 5060

Is it possible?
