10.1 Provisioning Hunt Order
The IP phone always attempts to use the first provisioning method listed below (DHCP
Option 160). If it cannot use this method, it attempts to use the second method listed below,
and so on, until it reaches a successful provisioning method. This is called the provisioning
'hunt order'. The 'hunt order' is:
1. DHCP Option 160 (see Section 10.2.1)
2. DHCP Options 66-67 (see Section 10.2.2)
3. DHCP Options 43 (see Section 10.2.3)
4. SIP SUBSCRIBE and NOTIFY Messages (see Section 10.2.4)
5. Static and Globally Accessible Domain (see Section 10.2.5 0)
6. Cached Addresses of the Last Provisioning Server Used on Reboots (see
Section 10.2.6)
7. AudioCodes Redirect server (see Section 10.2.7)
10.2 Dynamic URL Provisioning
Dynamic Host Configuration Protocol (DHCP) can be used to automatically provision the
phone. The DHCP feature can be configured using the Web interface or Configuration File.
