I work for a Cisco partner, so I am kinda on the enemy side of yours LOL..Well we typically deliver the following,
1. Phone number/user mappings
2. QOS config documentation for switches and routers (if IPT over wan)
3. A brief overview of CM and Unity upgrade procedures, OS updates etc (Typically the same documents from Cisco website)
4. Detailed spreadsheet with all IP addresses, passwords, etc.
5. Visio diagrams of the network.
6. Phone user guides, Voice mail user guides, Phone admin guides..etc..
Typically you cannot expect documentation for every single command that has been keyed into the router or switch unless you have paid for that many number of hours worth of documentation. Cisco's manuals are very detailed and do cover almost every possible scenario that an IP Telephony implementation can have.
