This allows the usage of standard compliant IP telephones using the open SIP standard, giving customers a
choice of endpoints of different manufacturers including special purpose devices like conference telephones,
hotel telephones or terminal adapters.
In order to use a non-Avaya SIP endpoint with IP Office, a "Third party IP endpoint license" is needed. This
license will continue to support endpoints based on the H.323 standard but will also be required for generic SIP
endpoints on IP Office. Avaya IP Office SIP telephones use the IP End Point license.
SIP Endpoint support is fully integrated into IP Office core. No other components are needed. SIP endpoints will
need VCM module capacity in IP Office like any other IP phone.
Next to SIP telephones, SIP terminal adapters are supported to connect analog telephones and fax machines.
This offers a flexibility to support Fax machines and Audio/T.38
SIP extensions function like any other IP Office extension: This means they
· Can make and receive calls to any other extension, independent of type of extension
· Delivers end to end Media just like any other IP telephone on IP Office. For calls between two SIP
extensions of a SIP extension and an Avaya IP telephone, the audio is transmitted end to end for basic
telephone calls. (Conferences etc. However require a VCM resource). See chapter "VCM modules" for
details
· Can use short codes and authorization codes like any other telephones
· Transmit In band call progress tones are delivered from IP Office
· A SIP telephones needs to register with IP Office like any other IP telephone, Authentication with
Username and password is possible
· SIP extensions support "auto create" in IP Office to make installation fast and efficient. Successful
registration of an endpoint will consume one third party license
· On one IP address, several extensions can register with IP Office, each consuming a license. This enables
the connection of SIP terminal adapters with more than one analogue port, giving a different extension
number to each of the ports.
