Making Calls via SIP Trunks
1. Lift the handset. Please make sure your Class of Service is allowed to access
SIP Trunk ARS.
2. Depending on the ARS policies and procedures you created, input the SIP
Trunk access code followed by the phone number, or simply input the
phone number. Press the # key to start dialing.
For example, if you set “7” in “Dialed String” as the SIP Trunk access code,
when you dial 7-44-2055551234#, the call to UK will get through your SIP
Trunk. If you set “01186” in “Dialed String”, when you dial
011-86-xxxxxxxxxxx#, all calls to China will get through the SIP Trunks.
