ATA Dialing Plan

[stevech]

I think that the OP was asking the following:

If he submits a ticket to support, will they be able to customize the dialplan on his ATA to explicitly support 7-digit dialing (without an extended pause after dialing the 7th digit)?

I can see something like this working if his ATA is a Linksys PAP2T, but can it work for Grandstream? I'm unclear as to their dialplan customization options. Even though the PAP2T clearly allows such customization (and if the other customers' ATAs support custom dialplans), is support able and authorized to make that change?

Yes, the above is what I am asking.
The impetus: Family needs to continue to have 7 digit dialing for same-area-code numbers, as is done on POTS. Without a dead-air timeout after dialing 7 digits. With a locked ATA, I cannot enter this dialing plan. Hence the original question in this thread. The sole area code for such 7 digit numbers is 858. Telling people here to deal with dead air, hit "#" or dial 10 digits needlessly will get me beat-up.
