The arrangement combines Avayas experience in IP telephone technologies with Junipers networking and security experience.
The new offerings include distributed IP telephony, secure IP telephony on any network, virtual contact center and enterprise mobility.
Enterprises can enhance these offerings by adding capabilities such as secure SIP communications and WAN acceleration.
By combining their technologies, the two companies aim to give enterprises ways to secure their networks while simultaneously increasing productivity, they said.
For example, an enterprise could install a firewall, router or a virtual private network from Juniper along with call center or converged communications technologies from Avaya to simultaneously enhance the security and performance of the network.
Avaya will provide professional services for the Juniper products incorporated in the joint offerings, including assistance in planning, designing and deploying the systems.
Avaya will also provide managed services for enterprises using Juniper networking products.
