Description

Configure sip to specify the Session Initiation Protocol (SIP) ALG on the device. Session Initiation Protocol (SIP) is a signaling protocol for initiating, modifying, and terminating multimedia sessions over the internet. By default, the SIP ALG is disabled for SRX5600 and SRX5800 devices. Use the CLI command delete security alg alg-name disable to enable the SIP ALG. IPv6 is supported on the SIP ALG along with Network Address Translation Protocol Translation (NAT-PT) mode and NAT64 address translation. The type of the destination-ip-address is changed from IPv4 address to IP prefix to support all kinds of IP addresses, and correspondingly a prefix is supported to allow multiple IP addresses.
