<p>We used to have Onvoy/Inteliquent SS7 via TDM, which was
reliable. Two A-Links, to two geographically diverse STPs. When
faults did occur, it was almost always with a carrier in the
middle (e.g., a fiber cut).</p>

<p>We are trying to move away from T1s. But some telcos that we
interconnect with have not yet realized the benefits of SIP. As
such, we still need SS7, in some form or another. Also, our LNP
lookups are over SS7.<br>

<p>Several months ago we migrated to SIGTRAN, staying with
Inteliquent, now called Sinch. They helped us through the
migration process, which went quite smooth overall.</p>

<p>The IP connections are over VPN tunnels, to two geographically
diverse VPN endpoints. We connect to two geographically diverse
STPs through those VPN tunnels (one STP per VPN tunnel). One
thing that I don't like, though, is that the VPN endpoints are not
located near the STPs. The STPs are located somewhat near me
(same state & next state over), but the VPN endpoints are
multiple states away, meaning the IP traffic trombones around the
US. This has not caused us any actual problems, though.</p>

<p>In general, yes, I would recommend Inteliquent/Since for
SS7/SIGTRAN. They have been good to us, and reliable.</p>

<p>Note: I was not involved in any of the money conversations. Just
the technical conversations.<br>
