Editorial #145: Look--If AT&T and Verizon Can Be Interoperable, Why Can't The VRS Industry Do It?


Recently, ATT and Verizon announced plans to make their new LTE networks interoperable (link). They are major giants in the industry and see a need for this. The VRS industry, while getting better, is still not 100% interoperable. We continue to see things like poor video connections, black screens, and address books that cannot be ported.

Dr. Z is challenging the VRS industry to move on—we all have to deal with a dominant provider who is causing all this. While they all including the dominant provider have been meeting periodically on SIP interoperability–there are areas within SIP interoperability that do not necessarily cover things like address book portability and video quality. The dominant provider uses proprietary (non-standard) codecs that affect video quality. The FCC is trying to let the VRS industry work among themselves on this–while waiting for the new things such as the Video Technology Access Reference Platform developed by the FCC which will not come into reality for at least a year or two. Until then, we will continue not to be functionally equivalent. This is 2014, not the 19th century. And we continue to be second class citizens because 100% interoperability is still not here yet. Is anyone listening?

When interoperability issues are resolved, we will finally achieve functional equivalence.
