The SPA-2002 is definitely generating the additional ringback. I verified
this by temporarily changing the frequency of the ringback in the SPA's
"Regional" settings.
I also verified that I am not using the "r" option in the Dial command. If
I were, however, only the Asterisk-generated ringback would be heard, and
then only until the call supervised (i.e. I would not be hearing two
distinct ring signals, and the ringback would not occasionally persist for
the duration of a call while still hearing the called party).
This problem is present only with the SPA-2002, and none of the other SIP
devices connected to this Asterisk server. I have also tried making
outbound calls via different service providers, all with the same results.
Thanks again.
Sincerely,
Trevor Hammonds
