asterisk

I picked up a Vertical Communications 7504-10 IP phone from a yard sale a little while ago on the assumption that since it was standards-based (SIP) that I'd be able to use it with Asterisk. Browsing around with google only revealed one thread where someone claimed that you could make the phones work, but said nothing about getting into the phone in the first place. But as it turns out, it's actually quite easy to configure these phones to work with an arbitrary SIP provider.
