[asterisk-users] Caller ID questions

[GlenM]

Hello Folks;

I have a dilemma:

I have a client with Asterisk 1.4x and he needs to have a record of all 
incoming calls - caller ID and date/time is sufficient. Since I am not 
an Asterisk wizard, I am doing it this way.

I set a cron job to tailf the last 10 lines of the Master.csv file and 
package those nicely in an email. However, I can see some inefficiencies 
in this. Main one is what if there are more than 10 incoming calls 
between cron runs?

So, questions:

1. has anyone done this?
2. is there a better way?
3. if so, can you 'skool' me ?

Thanks

B
