SIP and Sequenced Applications

At the core of SIP is its ability to support media of all different types. This is a significant improvement over previous VoIP protocols like H.323 which only support voice and video for its media streams. SIP doesn’t care if you are creating a voice call between two telephones, publishing a presence update, engaging in a video conference, or sending graphics commands to a shared whiteboard. SIP is completely media agnostic.

When Avaya put their Session Manager at the core of its Aura platform it took full advantage of SIP’s disregard for media content and created the concept of routing applications as part of a call flow. Avaya Aura Sequenced Applications are software entities that Session Manager invokes on behalf of the originator and terminator of SIP sessions of any type. These Sequenced Applications are able to take full advantage of both SIP and any programming logic applicable to a user or business process. For instance, a Sequenced Application can be written that uses a person’s presence (active, away, on-the-phone, on vacation, etc.) to route an incoming call to the appropriate destination. Another Sequenced Application could be written that identifies and blocks malicious calls. Yet another Sequenced Application might invoke a call recorder based on a set of predetermined criteria.

Since SIP is media agnostic and Sequenced Applications are based on SIP technology, Sequenced Applications themselves become media agnostic. In other words, a Sequenced Application that processes incoming voice calls could easily process incoming video calls or instant messages. This allows an enterprise to treat their employees and customers as users and not as a collection of devices. The rules that apply to a person are invoked no matter how that person communicates or is communicated to.

In these trying economic times businesses that are able to provide unique, better, more nimble, personable, and reliable services are rewarded while those that are not able to adapt perish. With Avaya Aura Session Manager, SIP, and Sequenced Applications at the core of an enterprise’s communication infrastructure there is no end to how a company can differentiate themselves from the competition. Backend business applications can be as much a part of a phone call as dial-tone is today. This is ground-breaking territory and only comes with SIP and the flexibility that Avaya brings to it.
