    Hi Ashar

    Nice work mate !!!!

    i was attempt for the voice lab 3 times and every time was different …

    the result sill fail !!!!

    and i did the last one on 23th of June , which is you just post the “MGCP Trouble ” on 22nd of June …

    this question i did not complete it as i was use debug mgcp input .. and after that near kill my HQ router ..

    but good to see your solution in here ..

    so did you passed the voice lab for this lab ?

      Hi Justin,

      Thanks for your feedback.

      I have been sharing solutions of what I use to come across in my day to day work. Most of it has been requested by my friends as you will not be able to find a comprehensive solution at one place for most of the things. I had to study different Cisco documents to put everything together.

      Quick hint for the MGCP debug – before you start ‘debug mgcp packet’ you must login to Putty session so that it saves the session. Please no questions regarding lab for reasons you very well know :)

      I will soon be writing CCIE Voice lab tips which may be helpful for all Lab takers.
      Thanks again and do let me know if you have any suggestions.

    I have one question in my mind running since long time. If any on e can help me in this….
    On HQ site globalization and localization is done…. So by hitting directories missed/received calls and dial, calls go through……
    But in Site B and Site C, when hitting directories missed/received calls and dial………….(for emgr, local and intrl calls) The call should succeed or not.
    Because for calls to succeed prefix 9 should be done.
    Does the mark get deducted in the lab exam if the calls are not working in this way….

  6. asharsidd says:

    @Royal – You will need to configure as per the requirement. If the requirement is that HQ users should be able to dial back from directories then you will configure it for HQ only, no need to do it for Site B and Site C if it has not been asked. If they ask that Site B and Site C users should also be able to dial back from directories then you will have to do it for both these sites as well. Please keep yourself confined to what has been asked, don’t get into configuring nice-to-have stuff as it will not fetch any points but it may take up your precious time which you will come to know by the end of the lab. You will not lose any points for not configuring anything which has not been asked. This is what I understand, offcourse I am not Cisco and cannot speak on behalf of them.

    Hello
    i am trying to implement cme with cue but i faced a problem . the problem is when i change the internal extensions to 3 digits format auto attendant do not forward calls to internal extensions Although i changed all extension in cme and cue to 3 digits format and changed the dial plan in cme which points to cue . what else i should do to get cue aa forward calls to internal extension
    thanks

  8. asharsidd says:

    Shehab, It should ideally work if you add proper extension – make sure you add dial peer which send incoming call to CUE

  9. strick says:

    Ash,

    excellent site, how about an ACCURATE how to for setting up extension mobility ?

  10. asharsidd says:

    Thanks for feedback.

  17. Dharambir kumar says:

    HI ALL
    i have one question please tell….
    there are 100 phones in a cluster
    all phones are registered to same server.working fine……but sudden 50 phones
    goes on registration process and go on ……those 50 phones are not able to register
    what might be issue…?

    Thanks
    Dharambir

  18. asharsidd says:

    HI Dharambir, Are these phones in same location? check the network settings for the ones which are not working and try to do a factory reset? Are you using DNS? This suggest a network issue to me so you should check the switch where these phones are connected..

    Hi all,

    Im preparing my ccnp voice and im really getting confused when configuring dial-peers. can anyone help me clarify the below: i believe the below is an incoming dial-peer but how come there is an outgoing translation pattern as well?

    dial-peer voice 1 pots
    preference 1
    destination-pattern 0T
    translate-outgoing calling 2
    incoming called-number .
    direct-inward-dial
    !

    one more thing, what does that match destination-pattern 12345T

  20. asharsidd says:

    Hi Joe

    I understand the confusion as dial-peers are a bit complex to grasp. I have written about dial-peers as well on this blog and would be helpful. Please see this:

    http://voiceonbits.com/2010/07/04/h323-dial-peers-made-simple/

    Regarding your question, this dial-peer is acting as an outbound as well as inbound POTS dial-peer. The direct-inward-dial & incoming called number . command means incoming call on E1 will come through this dial-peer and then will match an outbound VOIP dial-peer to go to Call manager, For outgoing calls from CCM to PSTN, calls will go out through this outbound POTS dial-peer after match that 0T pattern. The translate-outgoing will change the calling number so if you have 4 digit extension, it may change it to full PSTN number (depends how your provider would like to see).

    The destination-pattern 12345T means any dialed number which starts with ‘12345’ and then any number of digits will match this pattern and all digits will go to PSTN except ‘12345’ as they will be match explicitly. You may need forward-digits all or prefix 12345 to send 12345 as well.

    Hope this helps.

    Hi asharsidd,

    Good morning, i would like ask your help for my problem. I can not connect my web page Cisco Unified Communications Manager Administration.
    When i using my ip address its open the main web page, after that i try to click the link Cisco Unified Communications Manager Administration, to use my username and password and cant not open.
    Please, give me any tip

    Best Regards
    Al Monte

  22. asharsidd says:

    Hello, If I understood correctly you are getting an error when you are entering you ccm admin username password. If you are getting a database communication error then I would suggest restarting TFTP and if necessary restart CUCM but if you are not getting any error then you may be entering wrong username and password. You may reset admin username and password by logging in through CLI. You may find that method on this blog if you need.

    • al says:

      Hi asharsidd,

      No, the problem is that i can not open the link page Cisco Unified Communications Manager Administration, because this is the page where i can use my username and password to login in cisco callmanager admin page.

      Best Regards
      Al Monte

      • asharsidd says:

        Your statement is bit different of what you said initially.
        If that is the case then restart tomcat service from CLI

        utils service restart Cisco Tomcat

      • al says:

        Hi asharsidd ,

        I have tryed this command before, and the service Tomcat only stopped, and didnt restart. After that, i have applied the command utils service start Cisco Tomcat, just to start the tomCat service again.

        Best Regards
        Al Mont

      • al says:

        Hi asharsidd

        admin:utils service restart Cisco Tomcat
        Service Manager is running

        I have done now this command like you can show above, and untill now, i can not open the page.

        Best Regards

      • al says:

        Hi asharsidd

        there is another service that stopped:
        Connection Database Proxy[STOPPED] Commanded Out of Service

        What you can say about this service, because another one are running

        Best Regards
        Al Monte

      • asharsidd says:

        Connection Database Proxy[STOPPED] Commanded Out of Service

        That service cannot be at CUCM..are you looking at CUCM or Unity connection?
        See if you can ping the IP address of CUCM. Can you get to GUI of a subscriber? I would go for a clean cluster reboot if problem persists.

      • al says:

        Yes, i can ping to the router and server also, the ping works, but i can not get in to the GUI.
        I cannot access into Cisco Unified Communications Manager Administration, because the page cannot be displayed.

        Best Regards
        Al Monte

  23. al says:

    Hi asharsidd,

    When i try to use my Real-Time Monitoring Tool, to check what is happend, im receiving the following message:

    RTMT application cannot communicate with specified callmanager cluster(200), please verify the host ip address is correct and network connection is UP, and try again.

    Best Regards
    Al Monte

  24. asharsidd says:

    Try from internet explorer, firefox. Also add CUCM page under internet options >security > sites

  25. asharsidd says:

    You sure you are using correct format like https://IP/ccmadmin ??

    • al says:

      asharsidd,

      yes, im sure, and im one of the administrators, because the rest also found the same problem.

      Best Regards
      Al Monte

    • al says:

      Hi asharsidd,

      Yesterday, i also found this bug, and now i think that this can be one of the issues to get my web page admin down.

      HTTP Status 404 – /ccmuser/showhome

      ——————————————————————————–

      type Status report

      message /ccmuser/showhome

      description The requested resource (/ccmuser/showhome) is not available.

      ——————————————————————————–

      Apache Tomcat/5.5.17

  26. Why people still use to read news papers when in this
    technological globe everything is presented on net?

  27. Sydney says:

    Thank you for some other excellent post. Where else may just anyone get that type of info in such an ideal means of writing?
    I have a presentation subsequent week, and I’m at the look for such information.

  28. sushant says:

    hi sir , i have 4 fxo line in case of h323 gateway
    and i have 4 internal extension
    1001
    1002
    1003
    1004

    it is possible 1001 can use line 1 for incoming and outgoing
    1002 use line 2 for incoming as well as outgoing .
    same thing for other 2 extension

  29. asharsidd says:

    Hi Sushant, yes you can. In CCM when you add FXO port, under Port information you can select “bothways” to use FXO port for both inbound and outbound.

  30. asharsidd says:

    What is your gateway and what module you are using in its slot?

    • sushant says:

      I am using h323 gateway . module name vic2-4fxo card . I have 4 fxo line , internally I have 4 ip phones. I am trying to implement phone 1 can use inbound and outbound calling from line 1 .and same other extension 2 use line 2 respectively . in this gateway we have already 8 fxo line , 1 pri link total 12 fxo line and 1 pri ….but my concern only 4 fxo line

  31. asharsidd says:

    I will ask you again..which gateway is this? 28xx? 29xx? 39xx?

  32. asharsidd says:

    How are you getting the option for FXO on a SCCP 2911? what module you are selecting? I can only get FXO when I make the gateway as MGCP.

  33. sushant says:

    Hi dear i am facing very serious issue , in case of srst my sip phone not registering , sccp phones working fine. please help

  34. asharsidd says:

    You may have missed the SIP commands on the gateway, please add following and reload gateway and it should work.

    voice register global
    max-dn 10

  35. sushant says:

    we need to type only 2 commands it will be work , can u please give me full configuration,

    voice register global
    max-dn 10

    thanks in advance
