GRANDSTREAM GBX20 Network Extension Module
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.
GRANDSTREAM DOES NOT PROVIDE CON-NECTIONS TO EMERGENCY SERVICES VIA THE GBX20.
NEITHER GRANDSTREAM NOR ITS OF-FICERS, EMPLOYEES OR AFFILIATES MAY BE HELD

AR-RANGEMENTS TO ACCESS EMERGENCY SER-VICES IN ACCORDANCE WITH THE IMMEDIATE-
LY PRECEDING PARAGRAPH.
