OCS and CM 7X RRS feed

  • Question

  • We recently upgrade our Cisco Call Manager to Version 7X . Since the change now we cannot Dial 5 digit extentions within OCS to another OCS user. IS there Any settingin the new Call Manager that is different that we need to change or does the normalization Rule need to change? Odd since the 4 digit dialing and 7 digit dialing still work fine only the 5 digit is lost somehow. When you call with 5 digit the call does ring through to your desk but then when you pick up it just drops. The only change that has been made was the CM upgrade.

    Any help would be great.

  • If you are calling from and to an OCS Endpoint then the CCM cannot be the problem.
    Check you Location Profiles and verify the Normalization Rules
    Use Enterprise Voice Route Helper to check phone routing
    Use the debug logger on your FE to see the SIP messages and use the snooper tool (Resource Kit) analyze the logs

  • What is odd is ther fact the call does get routed correctly. There is just no audio. The call will stay on the line as long as you hold the phone and do not hang up. So the call is getting normalixed correctly then right? If you dial the person's 4 digit extention ther call goes through fine and the audio is fine. Only when dialing the 5 digit does it not come through with Audio.

    I looked at the Route Helper and doing a Ad-Hoc Test it works fine with the 4 digit extention for inside office shows the correct Sip and all. Putting in the 5 digit it comes up with normalizing it with the extra digit on the front of the but then does not show that is goes to a Sip address. So nto sure where to look or what to look for.

  • assuming that the 5 digit number is located in another location then the 4 digit numbers.
    Check whether there is a firewall in between the clients
    No audio is typically a firewall blocking issue
    Have you done tests the other way around => dialing from 5 digit to 4 digit number

  • Both the 5 digit and 4 digit extentions are bad even in the same regional office and across offices. What we use is a 4 digit extentions but calling cross office we put the extra digit on the begining of the nubmer with a office number at the start.

    So say Seattle office 4XXXX
    San Diego Office 7XXXX
    Miami office 5XXXX

    No firewall in between but we did make somre firewall changed Friday to try and fix and Audio Issue with Live Meeting. I will check into that.
