The GBX20 is not pre-configured to support or car-
ry emergency calls to any type of hospital, law en-
forcement agency, medical care unit ("Emergency
Service(s)") or any other kind of Emergency Ser-
vice. You must make additional arrangements to ac-
cess Emergency Services. It is your responsibility to
purchase SIP-compliant Internet telephone service,
properly configure the GBX20 to use that service,
and periodically test your configuration to confirm
that it works as you expect. If you do not do so, it is
your responsibility to purchase traditional wireless
or landline telephone services to access Emergency
Services.

NECTIONS TO EMERGENCY SERVICES VIA THE
