Thanks Jay, 

The link you sent provided the infor for me to verify my spa122 is working. 
I can connect at 33600, but no faster, but I'm ok with that. 
I still have more work to figure out why I can't connect via asterisk. 

I'll also have to understand the DialPlan syntax more. It seems something with
that might help me.

  VoIP Setup

Once you have web access to the SPA as above, you can configure the ports. We
will use the bogus number 9095551010, but if you want to use another one, just
replace it (in yellow) below.

1. Log into the web interface

2. Go to the Voice section, then Line 1
 1. Set Make Call Without Reg and Ans Call Without Reg to yes
 2. Set User ID to 100

 3. Scroll down and find Dialplan, and replace its contents with the following:
o (*xx|[3469]11|0|[2-9]xxxxxx|1xxx[2-9]xxxxxxS0|xxxxxxxxxxxx.|<9095551010:101>S0<:@127.0.0.1:5061>|)

 4. Under the Audio Configuration section, set everything that says Fax to no

 5. Click Submit and wait about two minutes, then click on the Voice tab again
if it doesn't redirect

3. Go to Line 2
 1. Set Make Call Without Reg and Ans Call Without Reg to yes
 2. Set User ID to 101
 3. Scroll down and find Dialplan, and replace its contents with the following
(it's different, so don't just reuse the first one!):

o (*xx|[3469]11|0|[2-9]xxxxxx|1xxx[2-9]xxxxxxS0|xxxxxxxxxxxx.|<9095551010:100>S0<:@127.0.0.1:5060>|)

 4. Under the Audio Configuration section, set everything that says Fax to no

 5. Click Submit and wait about two minutes, then click on the Voice tab again
if it doesn't redirect

4. Configuration is complete!






===============================================================================
 Troubleshooting

This should just work, but here are a couple things you can do if it doesn't:
1. Test basic dialing functionality:

 1. Get a plain, basic telephone and plug it into one port

 2. Try to dial 9095551010. Regardless of what's plugged into the other port,
you should hear ringing. If you hear busy signal or dead air, you missed a
config step.

 3. If you have a second phone, plug it into the other port. Test dialing
9095551010 from either one; it should ring the other set and you should be able
to pick up and talk.

 4. If all of the above works then there's nothing wrong with the ATA dialing

2. Apply data optimization settings:

 1. The instructions given earlier include the necessary step of disabling fax
detection, but if that isn't enough, you can do this too.

 2. In Line 1 and Line 2, apply the settings below. They will tell the ATA not
to try to "help" and should cause it to just pass through audio unmodified.

 1. After applying the settings to Line 1 and hitting Submit, make sure you
wait for the page to reload before moving on to Line 2.

3. In the Network Settings section:
 o Network Jitter Level: Extremely high
 o Jitter Buffer Adjustment: No 4. In the Audio Configuration section:
 o Preferred Codec: g711u
 o Second and Third Preferred Codec: Unspecified
 o G729a Enable: No
 o Silence Supp Enable: No
 o Echo Canc Enable: No o Everything that says Fax: No
 o Modem Line: Yes

3. If you're not getting any dialtone, check that the SPA has an active
Ethernet link on the blue port. If it doesn't have a connection and a valid IP,
it'll shut off the voice module.

 4. You will not get a 56k connection speed no matter what you do - the V.90
and V.92 specifications explicitly state that the modems you have ("analog
modems" are only capable of originating a 33.6 connection.  You need special
ISP equipment to originate a 56k connection.
