Hi Steve,
Thanks again for the response-- the answer you gave was more or less the answer
that I was expecting.
I was logging all packets to and from the phone, and I never saw an ACK from
the phone for the OK to Asterisk on the VM calls -- not an ACK directed to a

Hi Lincoln,
Asterisk was expecting ACK after sending the 200 OK message. After
repeated attempts at sending the 200 OK message and not receiving ACK,
it terminated the call. Are you able to do a packet capture on the phone
end? Mostly likely the phone is sending the ACK, but its either sent to

I'm not familiar with packets specific to Asterisk, but do have some

Hi Lincoln,
