<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 <i>can</i>
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?")<br>
