Could you please run "sip debug" and see if you have NOTIFY or INFO
messages flowing to the Grandstream and get error messages from Asterisk.

If you see something strange, please notify me. My Grandstream doesn't
respond properly to all SIP messages, and Asterisk notes a failure of
transmission and cancels the call.
