The SBC is enhanced to use the Max-Forwards header value received from the end-user, and decrements this header value by 1 before forwarding it to the other end-user. If the value received from the end-user is 0 or 1, the SBC will discard that request with an error response of "483 - Too Many Hops."
This feature will be supported only if rfc7332ValidateMaxForwards
is enabled through a CLI command on the Ingress side.
The RFC 7332 flag option is defined below.
Command Syntax
To set the flag:
% set addressContext <addressContext -name> zone <zone -name> sipTrunkGroup < TG- name> signaling rfc7332ValidateMaxForwards <Enable|Disable>
