We propose that the ALG only accepts commands from SIP Proxy
2 and provides responses for the corresponding commands.

Server Performance" in Proc.
The overall proposed procedure, which combines Ext-INFO and Hyb-INFO, as used at the SIP proxy
server, is shown in Fig.
Its SIP proxy
helps to more effectively route calls between servers in enterprise IP telephony environments for increased operational efficiencies and remote survivability.
a SIP proxy
server, can receive INVITE messages from any possible SIP sender UAs.
Packets transmitted between the SIP proxy
server and users should be classified and analyzed clearly to solve the vulnerabilities of existing SIP-based VoIP services.
ClariLink-V includes Internet connection load balancing and failover technology, a SIP Proxy
, SIP Registration Server and Network Address Translation (NAT) Proxy that allows SIP traffic to be load balanced and have real-time failover among multiple Internet connections to ensure call reliability.
ClariLink integrates voice and data network optimization, NAT and SIP Proxy
to keep call and data sessions active even in case of service provider outage
The EAGLE XG SIP Signaling Router (SSR) overcomes the lack of core signaling and session control in softswitch-based NGNs by serving as a SIP proxy
, bridging SIP- and SS7-based architectures to gain access to all routing information.
Distributed SIP Proxy
and Back-up Registrar Functionality First On-Board Application
Previously our SIP proxy
could route interactions based on where they were going in the 'to' field, but routing based on the source where multiple servers and gateways were involved would mean increasingly complex, thus time-consuming configurations," Staples said.
In addition to the introduction of the NetVanta 7060, ADTRAN also announced the availability of a number of new features for the NetVanta 7000 Series, including: SIP Trunking, SIP proxy
(eliminating the need for an external SIP ALG device), system scheduler, the ability to function as a wireless controller, and VQM.
