Have VoIPo ever updated their policies to allow the same deal to users of SIP phones (second line for the price of DID) to users of actual SIP phones?

I convinced my mother to use your service, but despite my and VoIPo's efforts at echo mitigation, the issue remains. I am sure replacing the ATA with proper SIP phones would cure the problem.

She currently has two phone numbers with VoIPo.com. Can we switch her to SIP phones and get the same rate, or would VoIPo want 2X the price for two lines because they are SIP phones?
