Re: [OSL | CCIE_Voice] Base configs and Dial Plan mapping
The one thing I'm really struggling with is mapping out my dial-plan during my read through of the lab. I would love to hear what others are doing. In my previous attempts, I find it very hard too, because the questions are verbose and I could either spend too much time reading OR not able to encode it into the table form correctly in haste OR simply skipped and waste too much time re-reading it. Here is my plan for my next attempt.I think the key is to have my pre-fabricate table then I will create my table quickly and ONLY adjust it while I read the question. So, I would quickly create this template. The list is there for easy cut paste. I will only complete Site A in during the lab, then I will just copy to SiteB SiteC. The rest is just modification of the table. (Note: I find that using TAB make it easier to align the columns, it could be 3 or 4 TABs.) In essence, focus on [1] Pre-fabrication [2] Quick to reproduce as a template. The rest is depending on how quick you can decipher verbose question and re-adjust the table.

Re: [OSL | CCIE_Voice] Base configs and Dial Plan mapping
Bill, You can read about the command here: http://www.cisco.com/en/US/docs/ios/12_3t/voice/command/reference/vrht_d1_ps5207_TSD_Products_Command_Reference_Chapter.html#wp1459139 The important bit is: When the dial-peer outbound status-check pots command is configured, if the voice-port configured under an outbound POTS dial-peer is down, that dial-peer is excluded while matching the corresponding destination-pattern. Therefore, if there are no other matching outbound POTS dial-peers for the specified destination-pattern, the gateway will disconnect the call with a cause code of 1 (Unallocated/unassigned number), So, when you have this command enabled (default) AND you have a single PRI AND that PRI is down, call set up request from UCM to the VG will result in a response of unallocated/unassigned. Why? Because we have told the router to monitor the status of the PRI and intelligently detect when it is down. When it is down, the dial-peer is no longer evaluated during call setup. By turning this off, we are basically telling the VG to go ahead and try to use the busted PRI. Which then results in a different kind of setup error that will let the CUCM know it should continue hunting through its RG/RL configuration. Lots of people leverage the service parameter I mentioned below to route around PRIs that are off line. That is probably fine for the purposes of the IE lab. I prefer to disable status checking at the GW level. -Bill -- William Bell, CCIE #38914 blog: http://ucguerrilla.com twitter: @ucguerrilla On Oct 18, 2013, at 10:06 AM, Bill Hatcher wrote: Bill, One other question, I'm not familiar with the command no dial-peer out status pots What's it do?

Re: [OSL | CCIE_Voice] Base configs and Dial Plan mapping
Hi Bill, I have adjusted it a little bit more to reduce the tab realignment while editing. It turns out that this creates more space where I can put in extra annotation such as route pattern. I think creating it from scratch could be done within 3 minutes. See a bit of a video clip here - http://www.youtube.com/watch?v=Cl9nANVgbms The text file can also available here - https://www.dropbox.com/s/t9bb2yo6x0wc66g/Dial-Plan-on-Notepad-Demo.TXT Regards, --Somphol.

I would love to hear what others are doing. In my previous attempts, I find it very hard too, because the questions are verbose and I could either spend too much time reading OR not able to encode it into the table form correctly in haste OR simply skipped and waste too much time re-reading it. Here is my plan for my next attempt.I think the key is to have my pre-fabricate table then I will create my table quickly and ONLY adjust it while I read the question. So, I would quickly create this template. The list is there for easy cut paste. I will only complete Site A in during the lab, then I will just copy to SiteB SiteC. The rest is just modification of the table. (Note: I find that using TAB make it easier to align the columns, it could be 3 or 4 TABs.) In essence, focus on [1] Pre-fabrication [2] Quick to reproduce as a template. The rest is depending on how quick you can decipher verbose question and re-adjust the table. Get the screenshot here is the following format is bad - https://www.dropbox.com/s/o1ftbh4katnhjcu/Quick-Dial-Plan-Template.jpg, The TXT version is here - https://www.dropbox.com/s/m2p2lte5ezk6q7d/Quick-Dial-Plan-Template.TXT I think Matthew Berry youtube is good too - http://www.youtube.com/watch?v=4mP5powuFUM.I just think it can be complement by the cookie-cutting approach to encode the table in Notepad that can be reproduced quickly. === The LIST === ISDN Unknown Subscriber National International Any === SiteA === Calling Called Emer 7D / Unknown / ISDN 7D / Unknown / ISDN Local 7D / Subscriber / ISDN 7D / Subscriber / ISDN LD 10D / National / ISDN 10D / National / ISDN Intl 1+10D / International / ISDN 011! / International / ISDN Another variation of the table format is too cater for TEHO scenario or BACKUP Gateway scenario. === SiteA === Calling Called Emer 7D / Unknown / ISDN 7D / Unknown / ISDN Local 7D / Subscriber / ISDN 7D / Subscriber / ISDN Local(Backup via SiteB) 7D / Subscriber / ISDN 7D / Subscriber / ISDN LD 10D / National / ISDN 10D / National / ISDN Intl 1+10D / International / ISDN 011! / International / ISDN Regards, --Somphol.

Therefore, if there are no other matching outbound POTS dial-peers for the specified destination-pattern, the gateway will disconnect the call with a cause code of 1 (Unallocated/unassigned number), So, when you have this command enabled (default) AND you have a single PRI AND that PRI is down, call set up request from UCM to the VG will result in a response of unallocated/unassigned. Why? Because we have told the router to monitor the status of the PRI and intelligently detect when it is down. When it is down, the dial-peer is no longer evaluated during call setup. By turning this off, we are basically telling the VG to go ahead and try to use the busted PRI. Which then results in a different kind of setup error that will let the CUCM know it should continue hunting through its RG/RL configuration. Lots of people leverage the service parameter I mentioned below to route around PRIs that are off line. That is probably fine for the purposes of the IE lab.
