[VoiceOps] CLEC - STIR/SHAKEN

Wed Aug 21 10:56:54 EDT 2019

My understanding is that the only VOIP carriers that can get an IPES OCN 
are Interconnected VOIP carriers. You have to get a certification from 
the FCC to become an Interconnected VOIP carrier because the 
Interconnected VOIP status allows you to order and manager your own 
NXXs.

The main network difference between a CLEC and an Interconnected VOIP 
carrier is that the CLEC has a direct connection to the PSTN via their 
own SS7 links and direct trunks to the ILEC. The Interconnected VOIP 
carrier gets their connection to the PSTN through a third party carrier 
that manages the SS7 links and direct trunks to the ILEC.
