SIP SIMPLE Client SDK

= XMPP gateway architecture =

The architecture of the SIP-XMPP gateway can be modeled in two different ways:

• Based on an XMPP component
• Based on an XMPP server (using server-to-server communication)

Both approaches are not mutually exclusive, they can both be implemented at the same time and decide which one to use with a configuration option to allow different deployment scenarios.

• SIP Application server which is also a XMPP component
• SIP proxy (registration, AAA and routing)
