asterisk users - May 2014 - Ghost calls on PBX

Hi all,

I have a user with an old Mitel PBX connected to a couple of SPA112's.  The
user is reporting that their phones ring several times a day and when they
answer the "call," all they hear is dial tone or busy signal.

Their PBX guy says that the SPA112's aren't providing line supervision
and
the PBX requires it.

Does anyone know how to fix this?  I'd also like to fix it from a
provisioning file, if possible.

Thank you!

Mike.

Most FXS ATAs do not support supervision so they don't work well when
plugged into a PBX's analog FXO (aka CO) ports.

If the Mitel can provide supervision on analog phone ports (i.e. FSX) then you
could use an ATA with FXO ports.   If the Mitel does not support supervision on
analog phone ports (FXS) this won't work either.

You could also avoid all the hassle, stress, and heartache from trying to stick
ATAs on a non-VoIP PBX and replace the Mitel.
