Linksys Dial Plan (Digit Map) - Prepend Area Code

Select the EXT 1 tab at the top of the page.

Under the “Dial Plan” heading:

Edit the “Dial Plan” copy and paste the edited text below. Edit the area code from either 414 (top example) or 252 (bottom example)

Original:

(*xx|[3469]11|0|00|[2-9]xxxxxx|1xxx[2-9]xxxxxxS0|xxxxxxxxxxxx.)

Appending 1 and Area Code and Appending Just 1:
(*xx|[3469]11|0|00|<:1414>[2-9]xxxxxx|1xxx[2-9]xxxxxxS0|<:1>xxx[2-9]xxxxxxS0|xxxxxxxxxxxx.)

(*xx|[3469]11|0|00|<:1262>[2-9]xxxxxx|1xxx[2-9]xxxxxxS0|<:1>xxx[2-9]xxxxxxS0|xxxxxxxxxxxx.)

Click "Submit All Changes" Button and wait for Linksys/Sipura device to reboot. Now you can dial either 10 digits (and the phone will append a '1') or 7 digits (and the phone will append 1+area code) and the phone will still send Junction Networks the requisite 11 digits.

Thanks Brian!
