<p>I'm not sure RBOCs have completely figured out how badly they've shot themselves in the foot yet. From my perspective, RBOCs have pushed everyone away so much, that the RBOCs now need other carriers much more than other carriers need them. I think the best way to deal with the destructive RBOC mentality is for all carriers to establish direct SIP connections with the carriers they get the most traffic from and pass the most traffic to.</p>
<p>CLECs and Interconnected VOIP carriers have been able to establish interconnections through the PSTN connection providers like Peerless (InfoBip), Inteliquent (Sinch), and Wide Voice for years. These PSTN connection providers eliminated the need for SS7 trunks because they host the SS7 piece of their network. For years, Wireless carriers have been establishing direct SIP connections with all the carriers they exchange traffic with the most. That has gotten them out of the CABS billing requirements so they don't have to waste money paying for someone to send their bills out and collect CABS billing.</p>

<p>We are also facing a large cost increase for SS7, specifically for the ISUP portion.</p>
<p>One of the frustrating parts, for us, is that we only need ISUP for connectivity with an RBOC, that has indicated that they want to do TDM trunking <u>only</u> (more or less) forever. And F-Links is not something they are willing to do. But, they <em>can</em> sell us an A-Link set.</p>
<p>(In addition to the RBOC, we still have TDM with another neighboring telco. We are working on converting that SIP. Even if we weren't going to convert it to SIP, I bet if I asked that telco to do an F-Link with me, that would respond with, "Yeah sure, which T1(s) should we put it on?")</p>
