Something that would help you GREATLY in determining what's going on
is to run a packet capture (such as with tshark or tcpdump) and read
the "conversation" between your device and Asterisk

e.g.: tshark -f 'port 5060' -w /tmp/test.pcap -S

Run the above command (if you have tshark, which is the terminal
version of Wireshark), perform a test call that duplicates this issue,
then press CTRL-C on the terminal, download /tmp/test.pcap, and open
it in Wireshark. Of course, you'll need to know how to read a SIP
conversation, but that's beyond the scope of this email
