An SPn service can be a generic SIP voice service. Examples of SIP/SP service include:

An extension from a PBX

A subscriber account with a service provider

Every SP service user account requires a user name, and oftentimes, a password for authentication. The service provider assigns an extension number or DID number to the user account. The assigned number may be the same as the user name of the account.

OBiTALK is a built-in service provided and managed by Polycom customers who can use the service for technical support and device-to-device calling among OBi devices.
