Much Better Study Session!

Thanks to the help of a co-worker I was able to resolve the issues I was having with my PRI configurations. I knew it was something to do with clocking but I was just too annoyed to research it yesterday. Apparently there's a command called isdn protocol-emulate that is used to make a Cisco router emulate as the CPE or as PSTN switch basically. I threw this on my router I'm using to emulate the PSTN (go figure) and did away with the T1 CAS's and provisioned them back as PRI ISDN lines. Sure enough the circuits came right up without any issues.

After messing with that and placing test calls, debugs, and etc. I was able to knock out 18 pages in the CVoice book, way better progress than yesterday. I'm also going through old CBTNugget videos on CVoice as there's some good refreshers on traditional telephony. My plan is to listen to one of the videos first thing in the morning time permitting. We're about to bring up our new remote site so I'm going to be knee deep in configuring Cisco devices and creating the dial plan in CUCM. This should be some good experience, we also plan on doing some clustering over the WAN by bringing up a CUCM subscriber at this new site, also good experience!
