[Asterisk-Users] Thousands of contexts?

[Manuel Wenger]

By reading the Wiki's I found out that an Asterisk server with many (>10000) extensions and/or SIP users can become slow when reloading. But what happens when you also have many contexts in extensions.conf? More precisely, one context for each SIP user?

I need this because I will have users with random usernames that they can choose, but I obviously cannot set that username as the outgoing caller ID when passing the call to our PSTN gateway. I need to change the CLI before dialling out. Now, every SIP user has his CLI, so I thought of creating a context for every user, where I would SetCallerID() before issuing the Dial() command. Obviously I would use some sort of script reading from a database to re-create the extensions.conf and sip.conf after making changes.

Do you see any issues which could arise? Is Asterisk going to crash, or is it just going to be slow when reloading?

Thank you for your help
-Manuel
