ignores the limit on ICMP errors.

active connection. It can range from 0 to 255 seconds.
Default: 0
Select IPv4 or IPv6.
Default: IPv4
If the phone is in dual-mode and has both ipv4 and
ipv6 addresses, it will always include both addresses
in SDP by attributes "a=altc ...
If IPv4 address is selected, then ipv4 address has
higher priority than ipv6 address in SDP and indicates
that phone prefers using ipv4 RTP address.
If the phone has only ipv4 address or ipv6 address,
SDP does not have ALTC attributes and RTP address
is specified in "c=" line.
