Understanding the code in "extension dial Strings"

[globatech_adm]

Hello,

im new in a company using adtran system. Im in the netvanta 7100 config manager, in the "IP phone config section" and im lookin at the configuration between 2 phones. I cant find whats the string difference does. One is like this : *[2-9][0123456789*].T3 and the other one have *[2-9][0123456789*]+T3. So my question is in the code of the strings, whats the difference between the dot and the plus and also some other have a comma like this: 9,411 and some other not 9411 on the same phone model (IP706). Wanna know what is the best practice for coding. Sorry for my basic english hope im clear, thanks for help!

The IP Phone Configs GUI page can be used to modify the extension dial strings for an individual IP phone.  For the ADTRAN IP 7xx phone model the correct extension dial string syntax would be *[2-9][0123456789*]+T3.  The +T3 at the end of this dial string instructs the phone to add a 3 second inter-digit timeout to wait for more digits to be dialed. 

The IP Phone Globals GUI page allows the modification of the extension dial strings for all the IP phones configured on the NetVanta 7100.  Under the Default Settings tab is listed the extension dial strings.  You will see that extension dial string as *[2-9][0123456789*].T on this GUI page.  The .T in this case also instructs the phone to apply an inter-digit timeout.  When the extension dial string settings are applied from this GUI page the strings are converted to correct format for the IP 7xx phones ( in this case **[2-9][0123456789*]+T3). 

The , in the extension dial string 9,411 instructs the phone to play a dial tone after the trunk access digit 9 is dialed.

As far as best practices if the system needs to be configured to dial a 9 for external calls, then the default dial plan on the NetVanta 7100 is already configured correctly.  No changes would need to be made to the extension dial string configuration for this setup.

Thanks

Thanks Charles for your answer really helpful. Now my question is if the strings code in the global config .T are supposed to be converted in +T3 in the ip phone config but are not, do you think the IP 706 phone can execute correctly the string with the dot or it will not? Think i can count half of the IP706 with the dot default setting and the other one with the +T3 you have any idea why config didnt reply exactly on the different phone? Thanks

The IP 706 would not execute the .T correctly for that dial string.  To correct this you can navigate to the IP Phone Globals GUI page and on the Default Settings tab select Apply Settings To: New and Existing Configurations.  Then click Apply and this will overwrite all of the existing phone configuration files with the extension dial strings configured on this page and will convert the dial stings to the format used by the IP 706 phone.

Thanks,

Charles

Ok thats what im thinkin but this action will automatically reboot all the phone?

avlogadm This step will not reboot all of the phones.  However, you would need to reboot the phones for the phones to receive this dial sting change. Thanks, Charles
