Cincinnati Bell: Other Tier 1 carriers discussing HD voice peering

Cincinnati Bell’s Evolve hosted HD voice service is currently a stand-alone island, but other carriers – outside of the usual suspects – are starting to kick around the idea of peering HD voice calls directly.

Mike Herman, product manager for Evolve, said that conversations about HD voice peering had literally started in “the last 45 to 60 days.” 

Since Cincinnati Bell already exchanges long-distance calls via IP and SBCs for least-cost routing, moving up-stack to support full-blown SIP peering for HD voice wouldn’t be technically difficult.

“We’ve talked to a few of them,”  Herman said, without mentioning specific names. “We’ve been approached by a couple of carrier partners, ‘Do you think there’s value in [HD voice delivery]?”

Carriers are kicking around the idea to see if there’s more “value” in HD voice peering, either something that could be a value-add (i.e. charge more) service or something to help sell more services.

Discussions are taking place with Tier 1/Tier 2 service providers directly and outside the framework of Voice Peering Fabric (VPN) and Xconnect aggregation services.  It is also taking place outside the context of the Sprint PIN network; Sprint currently provides vanilla VoIP peering/exchange services and does not support G.722 or other wideband codecs at this time.

One attraction is for service providers – potentially including Cincinnati Bell -  to deliver their own SIP/VoIP aggregation service internally, and then simply peer that service to other carriers
