Gateway Issue w Toshiba VoIP Phone

I got it working finally after discovering the MAC# labels on the voip phone is completely different than the MAC# that the 2Wire identifies when connected by Ethernet port.  Originally assumed it was a MAC # for ATT provided device since didn't match anything of my company or personal devices.  Once that riddle solved I opened access to through firewall via DMZplus setting. 

Thanks for your assistance and patience...lesson learned on trusting labels.     

PolterGeist - IP phones can be tricky getting everything set up right. You could check with Toshiba to see if they have any suggestions.

Thanks...I've pulled my hair out and now regretting changing internet service providers and may just cancel Uverse and revert back to old provider over this since I was assure my VoIP phone wouldn't be an issue from ther very beginnging.  My IT is seeing if our Toshiba phone system vendor has any ideas...rediculous experience so far due to time I've waisted with this VoIP connectivity issue.

Well I wish is was an issue with my IT department, but after spending hours on the phone with multiple ATT techs and the TechConnect service no one has ownership of the solution.  The best I can tell is ATT requirements for the 2Wire 3800HGV-B they deploy purposfully prevents usage of non ATT voip phones.  The solution someone provided with the 2Wire 3600 doesn't work for the 3800 as it does not even recognize a device present for the port the voip phone is plugged into.  But this is one riddle I'm done spending any more time on and going back to comcast service/modem where my voip phone was a non issue and just plug and play.

Now phone equipment swapped out...just ordered Uverse TV and internet for my home office to replace comcast.  I have a voip phone my company sent me to use for home office and works fine when plugged into comcast modem, but not with 2Wire.

Meant "no" phone equipment swapped out.

Here is a link to where someone helped a user connect a VoIP Toshiba phone to their office phone system thru a 2 Wire.  It's a differnt type Toshiba phone but the ports needed should be the same for all Toshiba phones.
