[Asterisk-Users] Size limitations of extensions.conf

[voiplist]

Can someone tell me the size (or any other) limitations for the extensions.conf?

We have managed to keep our file pretty small thanks to AGI but we are
about to setup a bunch of call restrictions based on area and country
code.

One line per area code in the US alone adds a LOT of text to this file.

Is it a bad thing to have 5 or 6000 lines of text in your
extensions.conf on a production system?

Will it affect the performance?
