Phone Line Issue w/Obi 110
azrobert:
I configure my OBi110 directly using the Web interface. There is nothing wrong with using OBiTalk to configure your devices. I just prefer not to be tied to another service. Since I don't use OBiTalk I don't know what the wizards change. It looks like the Phone Port Primary Line was changed to SP1 Service because they are suggesting you change ITSP A DigitMap.
IMHO this is how your OBi110 should be configured.
Enter OBi Expert.
Click Service Providers, Click ITSP Profile A General
Change DigitMap to: (xxxx)
Click Physical Interfaces, Click Phone
I'm guessing the Primary line was changed to SP1
If it's not PSTN LINE, just check the box under OBiTalk Settings.
This will set Primary Line to the default of PSTN Line.
This is the default Phone DigitMap:
([1-9]x?*(Mpli)|[1-9]S9|[1-9][0-9]S9|911|**0|***|#|**1(Msp1)|**2(Msp2)|**8(Mli)|**9(Mpp)|(Mpli))
Change it to:
((Msp1)|[1-9]x?*(Mpli)|[1-9]S9|[1-9][0-9]S9|911|**0|***|#|**1(Msp1)|**2(Msp2)|**8(Mli)|**9(Mpp)|(Mpli))
This is the default Phone OutboundCallRoute:
{([1-9]x?*(Mpli)):pp},{(<#:>|911):li},{**0:aa},{***:aa2},{(<**1:>(Msp1)):sp1},{(<**2:>(Msp2)):sp2},{(<**8:>(Mli)):li},{(<**9:>(Mpp)):pp},{(Mpli):pli}
Change it to:
{(Msp1):sp1},{([1-9]x?*(Mpli)):pp},{(<#:>|911):li},{**0:aa},{***:aa2},{(<**1:>(Msp1)):sp1},{(<**2:>(Msp2)):sp2},{(<**8:>(Mli)):li},{(<**9:>(Mpp)):pp},{(Mpli):pli}
I added 1 rule to the beginning of the DigitMap and OutboundCallRoute
Under Physical Interfaces click LINE
Change the DigitMap to:
(xxxxxxxS4|[2-9]xxxxxxxxx|1xxxxxxxxxx)
That's it.
Now you can dial 4, 7, 10 or 11 digits.
4 digit numbers will be routed out SP1.
7, 10 or 11 digit numbers will be routed out the Line Port.
You can dial # to get the POTS dial tone.
You will get an error with any other number.
If you have additional requirements, list then and I will modify the above example.

A few things. When you say you can just dial a 7, 10 or 11 digit number and it goes out the line port but then say you can press # to get local POTS dial tone, what is the difference there? I mean, the line port IS the local POTS dial tone and the only variation of dialing numbers is 7/10/11.
Also, what about a 3 digit number (911) in your scenario? Is that going out the line port (local POTS dial tone) as well?
Finally, does this actually address my issue by doing this swap (echo, dropped words on a call, etc) or is it all just to make the call path easier and swap what the default methods are? If the latter, that's really not my issue as the reason I posted was to get improved quality on POTS calls.

If you get this problem resolved, you don't need to dial # to access the POTS line. Set the Phone Port Primary Line to PSTN Line. Now any number dialed will be routed to the POTS line. It would take a few simple config changes to route 4 digit numbers to the trunk connected to the corporate office.
The above is what I said in my first post. We then got off the purpose of this topic. The answer to your question is no. This will not resolve your problem.
I list # to show you can still use your current method to call out the POTS line.

This may be a dumb question but, are you sure there isn't some connection between the incoming POTS line and the line out to the phones when using the Obi110?
I had a situation once with another ATA. The ATA had intermittent issues when connected through the phone lines in my house but no issues when just one phone was plugged directly into the ATA. There is a lot of phone wiring in my house that was all connected even though many of those runs do not terminate to anything. By disconnecting all unterminated runs (those that did not go to a phone jack), the problem was solved. My assumption was that the was added capacitance created a problem for the ATA.
I would expect calls over POTS not to have a problem with the Obi which is why I'm throwing out other ideas.
DanielG:
No it's not an issue with the POTS line at all. This happens at multiple locations and at the location that has the most issues we even ran new copper from the DMarc to the Obi 110. It's not related to the line at all (again, if we bypass the Obi and plug the AT&T Dect 6.0 phone directly to the POTS line we don't experience any of these issues.
