To have an IP phone (i.e. 7960) auto select a line when the phone goes off hook use the auto-line <line number> command under the ephone <num> configuration. The default behavior is to require a line to be selected .

Initial MGCP Configuration Commands for PRI
PRI commands (2):
pri-group timeslots 1-X service mgcp <- T1/E1 Controller
isdn bind-l3 ccm-manager <- Serial Interface
CCM-Manager commands (4):
ccm-manager fallback-mgcp
ccm-manager music-on-hold bind loopback0
ccm-manager redundant-host <PUB IP ADDRESS>
ccm-manager mgcp
MGCP commands (6):
mgcp call-agent <SUB IP ADDRESS>
mgcp bind control source-interface lo0
mgcp bind media source-interface lo0
mgcp ip qos dscp cs3 signaling
mgcp dtmf voip codec all mode out-of-band
mgcp
It’s simple to remember since it’s 2 PRI related commands, 4 CCM-Fallback commands and 6 MGCP commands. An additional command that is useful is the “isdn outgoing display-ie” command under the serial interface for passing display information elements.
One of the common issues with B-ACD scripts is that people forget to reset the script after making changes. The common way to do reset the script is shown below:
BR2#show call application sessions
Session ID B
App: bacd
Type: Service
Url: flash:app-b-acd-2.1.0.0.tcl
BR2#call application session stop id B
Stopping session
BR2#

Pay close attention when cutting and pasting examples from the DocCD that every command is taken. Quite a few configurations from the DocCD can not be pasted directly into the IOS as commands are either incorrect or missing mandatory parameters.
For basic VLAN configurations, I don’t think the type of SUP (sup1a, sup2) matters. However, when configuring QoS, you would need a PFC (Policy Feature Card).
MSFC is for L3 routing features which one could live without for practicing for the Voice lab.
Question:
Some people say that if you want to pass the lab exam you must be able to finish everything within six to seven hours and set the rest of the time for troubleshooting. What are your thoughts on this one please?
Answer:
It really depends – I have seen candidates who finished everything shortly after lunch and still not passing, yet some people have passed without finishing the entire exam.
I could not stress verification enough, as many candidate unfortunately fail the lab because they did not recover from configuration mistakes (sometimes as simple as a typo on ip address). With no partial credits, these mistakes can add-up to your disadvantage rather quickly.
So, verification (configuration validation, troubleshooting, and recovery) is as important as configuration, and my advise to candidates is that you should devote equal, if not more, amount of your preparation time on how to verify than on how to configure.
With that being said, let me be the first to admit that the Voice lab is configuration-heavy – by this I meant that candidates must dedicate a substantial amount of time merely typing in the required configurations. With the current lab content structure, I advise candidates to practice on a configuration scheme to save time by minimizing the frequency of “touching” any configuration page: think updating each IP phone configuration page only once or twice instead of doing it every time after you update a field on the page.
This leads to another excellent discussion point: in a test to assess candidates’ technical knowledge, candidates should not be “burdened” to come up with a configuration scheme to speed things up. In other words, candidates’ typing speed, to say the least, should not matter too much in them passing or failing.
So, this is for all who’s intersted, what is your thoughts on being given a lab test with certain basic parameters, such as IP phones, device pools, etc., preconfigured?
Your thoughts on this one please? And just a reminder that “it depends” is reserved for the moderator and myself on this session. 🙂
Just kidding, all responses are appreciated and if you could provide some thoughts behind your opinion it would be even better.

To change the interdigit timeout value go to Service -> Service Parameters -> Select the CCM server and the “Cisco CallManager” Service. Once there do a “ctrl-f” to open up the find window in Internet Explorer. The enter 302 in the “Find what:” box and then click “Find Next”. This will bring you down to the “T302 Timer (msec)*”. Enter the desired value in milliseconds and click “Update”. Finally restart the CCM service. Application -> Cisco CallManager Serviceability -> Tools -> Control Center. Now select the server then click the radio button for Cisco CallManager and finally “Restart”.
From CCM in regards to the T302 timer:
T302 Timer : This parameter specifies an interdigit timer for sending the SETUP ACK message. The timer restarts each time Cisco CallManager receives a digit. When this timer expires, Cisco CallManager routes the dialed digits. For exact timer definitions, refer to the Q.931 specification.
This is a required field.
Default: 15000.
Unit: msec.
Minimum: 3000.
Maximum: 75000.
