simtech: handle 'VOICE CALL' URCs

Just processing and parsing them for now, so that they don't interfere
with other commands:

  $ sudo mmcli --call 1 --accept
  error: couldn't accept the call: 'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Failed: Couldn't accept the call: Unhandled response '

  VOICE CALL: BEGIN''
