asterisk users - Sep 2004 - Newbie 2 PBX VOIP, protocol ?'s using Cisco 827 7910

I am replacing a dead pbx with *. There are four lines I will be using.
There is a Cisco 827-4v already in place so I will move the lines from
the pbx to it.

I am working with Cisco 7910 phones and I understand they use the
Skinny/SCCP protocol. I am not sure if I should use chan_skinny or
chan_sccp?

However my main question is with communication. Do I need to use the
same protocol between the Cisco 827-4v and *, as I am using between *
and the 7910 phones?

I read through the pdf docs and looked around but in this situation I
assume all traffic and etc will go through *?

Or will it just talk to * in the loop and use the Skinny/SCCP to talk to
the router.

Now I have come across 
http://www.loligo.com/asterisk/cisco/827-4v/cisco-827-4v-with-asterisk-version1

Which seems to use SIP between the router and *. Not sure if they were
using SIP to communicate to the phones or not.

Please excuse my ignorance in this matter I am a newbie to PBX, VOIP,
and *. There is allot to take in at once and I am doing what I can.

(chan_sccp developer hat on)
Chan_sccp, it supports more features of the phones (and several more are
on the way if I can find someone in Australia (pref Melb) who can loan
me a 79XX phone for a few weeks to debug them)

No, asterisk can protocol and codec convert.

Yep, asterisk can be set up so that isn't the case but for reliability
reasons that usually isn't done.

Router <--SIP--> Asterisk <--SCCP--> Phones
Hope that helps

Well, you've at least tried to ask intellegent and reasonable questions.
