Hallo good people,

I´ve been configuring ip phone for a couple of weeks now

and I´m faced with a question: In the phone configuration

process where do you configure the phone to make calls to

cell phones or fixed lines?

the phones are 3911...




Thanks in advance.

    Hi Carlos,


    Basically, you need a "gateway" to connect the IP network to the Telephone company network. The IP net and the Telephone Net are two different worlds.


    Do you own a gateway? Are you asking for specific instructions as to how to configure this?


    If you are not familiar with the term gateway, take a look in the CCNA Voice book chapter one.

    Hi Carlos..


    I beleive you are lookin at cmc code or a Fac code for the phones to dial out.


    For this

    1. need to configure route pattern with the enable cmc or fac selected

    2. Put the route pattern in a  partition

    3. Assign the partition to a calling search space

    4. Assign the css to the phone

    5. Assign a cmc/fac code for the user

    6. When the phone dials out the particular pattern it will ask for the code and once the user enters the code the call will sent to the gateway.

    Hi Carlos,


    Please run a dialed number analyzer test on the number which you are dialling using the same css which you have assigned to the phone. This will show you the pattern which the call is taking and make sure this pattern has the enable cmc or fac enabled in it.

    To go to DNA

    https:\\ip address\dna - if dna is not installed need to install it from the tools page.
