The modem is returning <DLE>u which indicates a transmit buffer
underrun. That is, the modem is waiting for your application to supply
voice data for transmission.

AFAIK all control codes must be prefixed with <DLE>, so to end the
transmission you would send <DLE><ETX>.

You may also check whether you can set a voice inactivity timer,
probably ATS30=n, where n = timeout in seconds.
