After finishing my previous post I decided to also write a small how-to about configuring Asterisk and flashing the cisco 7912G with the SIP firmware.
Ingredients for today are:
| A cisco 7912G IP phone | [Get it here] or [here] |
| SIP firmware for the 7912G phone | [Get it here] or [here] |
| Asterisk package for OpenWrt | ipkg install asterisk |
| Asterisk voicemail package for OpenWRT | ipkg install asterisk-voicemail |
| Asterisk sounds package for OpenWRT | ipkg install asterisk-sounds |
| A small amount of time |
