[VoiceOps] SS7 problems

[Dave Frigen]

I know SS7 is not a big part of the voice world for many of you, but for
those of you still exposed to it, just curious if anyone experienced any
problems with SS7 signaling in the past couple of days where Terminating
signaling times out and a 2nd retry and new call set up for the call
delivery occurs. The result was the phone ringing the customer, no one
there. Second attempt successfully (if multiline hunt group) comes in on
next line/trunk.

 

Trouble tickets reported:  Customers complaining about phones ringing, no
one on the other end.

 

We traced the issue upstream in the SS7 signaling. The signaling was timing
out after 15 seconds, creating call retry. We had our SS7 provider look into
it. No trouble found, but the "gremlins" mysteriously disappeared after the
testing..concerned trouble may reoccur.

 

Any reference to anyone else experiencing these issues recently would be
appreciated.

 

Dave
