[Serusers] Use of fifo for registration :ul_add: command tutorial

Hi all,

 

I would like to use ser_fifo to register a user; I think the :ul_add:
command is the clue, but I don't how to use the fifo to do this.

 

My aim is to do the following:

I have a Voip gateway on a customer with a lot of phone number (700) and I
would like to authenticate each number. Unfortunately I have to add a small
amount of configuration on the voip gateway each time I add a number (uri),
moreover I'm not sure this gateway will work with so many numbers, and the
bandwidth needed to register each number every 5 minutes will be wasted.

 

The idea is to challenge only one time the gateway and then in ser.cfg if
the challenge succeeds I execute a script to register by bulk all the
numbers enclosed in a file on the proxy. To do this I have to pass arguments
to the fifo using the :ul_add: command, but this is where I'm stuck.

 

I've done this:

 

echo :ul_add:receiving_fifo > /tmp/ser_fifo

echo location > /tmp/ser_fifo

echo 100 > /tmp/ser_fifo

echo <sip:100 at 10.1.1.1:5060> > /tmp/ser_fifo

echo 300 > /tmp/ser_fifo

echo 0 > /tmp/ser_fifo

echo 2 > /tmp/ser_fifo

 

but it does not work, I think this is due to the receiving_fifo, I have to
do something with it to process the response of SER, but what ??

 

I know I can use the following command to workaround the pbm:

Serctl fifo ul_add location ...

 

But it requires one process each time I register a number, and it takes 1
minute on a Celeron 700 for 500 numbers (30 % CPU), and I think using the
fifo is a more suitable solution (less CPU consuming).

 

Thanks for your support,

 

Rodrigue

 

PS: I would like to register every 5minutes,cause the customer gateway is
able to redirect to PSTN in case of failure.
