[Asterisk-Users] Extensions / Contexts

[Eric Wieling aka ManxPower]

This is crap.

Contexts are DESIGNED for segmenting Asterisk to provide service to 
multiple companies with overlaping extensions numbering space.

extensions.conf and voicemail.conf both support contexts.

sip.conf, iax.conf, etc do not, but if you are servicing multiple 
companies you don't want to make the sip or iax username the same as the 
extension.

What we do is make the sip username to be the serial number (or MAC 
number) of the device.
