Abstract

The current state of SIP is rigid and static. When transitioned to a dynamic state, which includes a Dynamic SIP ID Allocation Server, SIP IDs will be handed out dynamically. With this dynamic association, there is a need to associate these dynamic IDs with something easily remembered such as a person's name. For example, a person has been initially assigned the SIP ID of 8200@10.0.0.1. A subsequent assignment gives 9400@192.168.0.1. How do we dial this person's extension without knowing their SIP ID explicitly? Very much like DNS, we associate a person's SIP ID with their name, say John Smith. Now when Mr. Smith connects at work and gets a SIP ID, we can call him at "John Smith" with a lookup to the DSNS server and get his 8200 extension. When Mr. Smith returns home and is assigned a SIP, we can still call him at "John Smith" and the DSNS server returns his 9400 extension. A dynamically allocated SIP ID needs to associate to a unique identifier. Very much like how IP addresses are associated to a common name, this can be applied to SIP IDs.

Dynamic Session Iinitiation Protocol (SIP) Name Service (DSNS)

The current state of SIP is rigid and static.  When transitioned to a dynamic state, which includes a Dynamic SIP ID Allocation Server, SIP IDs will be handed out dynamically.  With this dynamic association, there is a need to associate these dynamic IDs with something easily remembered such as a person's name.

For example, a person has been initially assigned the SIP ID of 8200@10.0.0.1.  A subsequent assignment gives 9400@192.168.0.1.  How do we dial this person's extension without knowing their SIP ID explicitly?  Very much like DNS, we associate a person's SIP ID with their name, say John Smith.  Now when Mr. Smith connects at work and gets a SIP ID, we can call him at "John Smith" with a lookup to the DSNS server and get his 8200 extension.  When Mr. Smith returns home and is assigned a SIP, we can still call him at "John Smith" and the DSNS server returns his 9400 extension.
