that's the same conclusion i came to, but why is this happenning ? changing
loopback cables didnt help either.

tried two suggestions, one was yours with all spans set for timing=0, and
the other was to have one set to 0, one set to 1, one set to 2 and one set
to 3. in both cases, the symptoms persisted.

aye, double checked this as well.

there're none for those portions. nothing gets printed, even though pri
debug span is on. i could turn on pri intense debug, but would anyone be
able to assist in deciphering it ?

i've amended that, still no luck.

i have. see attached zaptel.conf and zapata.conf.

i left it out for verbosity reasons. it does exist in zapata.conf.

what if we dont have DIDs, but want it answered anyways. as the verbose
output above shows, asterisk knows about immediate=yes and pushes it to the
s extension correctly.
