I have one incoming line with DSL and phone associated. An ATT tech separated the voice from data at the exterior, so that may be a little weird when finalizing everything...
I have had lots of problems when calling ATT about ANYTHING, so I am hesitant to start the porting process.
I also want to disconnect phone service and dry loop the DSL.
I have read to call ATT first, some say to initiate the porting with ooma first.
Any advice appreciated.
It was done when promised and with no issues. After the port completed, I did have to power off the hub for about 70 second and power it back on to solve the problem where my calls to my ATT number would go directly to the ooma voicemail and not ring the house.
I have cable, not DSL so your mileage may vary.
I would suggest that you call att and let the rep know exactly what you want to do, that is
* keep the DSL service, hence dry loop dsl
* keep the number to port it out to other carrier.
* no cancel of any services.
In my case, the rep was very helpful and probably done it before. She transferred me to a tech rep who would get it done. The tech rep told me she would do two things:
1. put my dsl on a new accout, ie a new phone number for dsl service
2. create a dummy account to hold my current number to keep it until the porting process is completed.
the phone account will be cancel when the porting complete.
The call last appox. 20-25 min including waiting on hold.
It takes 10-11 days to complete the dry loop: my phone went dead but dsl continue without interruption.
For att dsl, it's better to have the dry loop done before the porting happens.
Don't forget to follow up with att for the final bill/statement.
YMMV and good luck
