Re: Any info on why? The play to go with BYOB is already the way I use Callvantage. I is NOT My understanding that anything but the LAST MILE of Callvantage goes over the PUBLIC net as that would be SKYPE! And its worked without a pop, snap or crackle for 4 years- and I am a SW network engineer for more than 20 years.
The IP rides in the DOCSIS frame for the last mile on a shared media (public net) but once in the CO it is routed onto an ATT VPN which is ATT Backbone-maybe they tell U-verse people that to calm them. QOS is not needed in cable in last mile much as its such a fat pipe-with video recently I have had some upstream congestion maybe during a peak 20 mins. a day...usually not bad but tells you they need to fix DOCSIS to do some prioritization in the VOIP gateways and from the CO to the CPE. Anyway point here is I can not GET ATT DSSL as I am in VZ land but I CAN GET CALLVANTAGE AND I CAN GET ATT WIRELESS so the customers ATT would want would be to STEAL VZs cellular customers especially the ones already lost to Callvantage or Vonage as hey are RIPE for the picking. OF COURSE THAT WOULD BE VIA FMC
and yes Femtocells would do it--ONE PHONE for Cell and home...
and likely unlike T-Mobile they would not use DUAL MODE hand sets but the iPhone could takk direct to femto tower. Finally iPhone operation when in HOME mode runs ENHANCED FEATURE SET due to the faster and CHEAPER BACKHAUL. Home calls are al free as are premium features that are more when "wandering" that is moving outside of a hot spot in the ATT network..
once at work...a picocell device could then take over and offer free calling within your office net--later..for now I see a DOUBLE PLAY Move
to retain and expand STICKY CELL SERVICE and to admit as well DSL is a lame way to deploy so expand business as we lay fiber and pay for it via cells etc.
Saying BEST EFFORT confuses people--the only BEST EFFORT for VOIP is when its over DSL if the traffivc is not tagged as VOIE in the TOS feild
from the DSLAM (if its IP--or if ATM tagged CBR) then its BEST EFFORT, purely an issue from the CO to the CPE---as far as from CO to
the core---come on boys-CALLVANTAGE AINT GOING OVER THE PUBLIC NET
NOR IS U-VERSE --they are both mapped next hop to the ATT IP BACKBONE...
otherwise the calls would be FREE LIKE SKYPE_-even SKYPE has paid calling where they go over say LEVEL 3s network and do so EXACTLY in way I say via routing to LEVE:L 3s VPN.....
