Quite the opposite. SS7 is used extensively on the interconnect
side. The more the landline subscriber base erodes and voip
subscriber base grows, the more demand there will be fore voip
operators to interconnect with existing landline operators.<br>
<br>
Also, from a development perspective, those that using libss7 are
likely to be the same people buying Digium's more expensive hardware
(Quad and Octal port T1/E1 with echo cancellation, high-density
transcoding, etc.) so it is not about how many people use libss7 so
much as how much revenue the userbase of libss7 generates for
Digium. In my desk drawer, I currently have three spare TE820BF
cards (i.e. just spares and excluding the many ones I have in active
deployment). I buy them regularly. If libss7 ceased to exist, so
would my spending on Digium TE820BF cards.<br>
<br>
As for the previous comment, I've used both chan_ss7 and libss7 in
production environments and found both to be very stable if set up
correctly (and provided you don't use chan_ss7's cluster features).
chan_ss7 seemed more feature-rich a few years ago. The key reasons I
changed from chan_ss7 to libss7 was that I needed T.38 gateway
features available in Asterisk 10/11 and that there was a bug in
chan_ss7 where it sent empty optionals section. But to suggest that
chan_ss7 is unusable is really unfair.<br>

<div>In my opinion chan_ss7 is full of bugs, lots of
crashes.<br>
libss7 has bugs, but it doesn't crash.<br>
libss7 has never been a mainstream digium project, due
to limited need for ss7/isup versus ISDN / MFC R2.<br>
At the same time, the bugs / bad features in libss7
don't make it unuseable.<br>
My impression is that libss7 was a pet project from
Matthew Fredrickson.<br>
