RTP tab
With the RTP tab, you can configure Real-time Transport Protocol (RTP) identity settings
for the phone.
Number of initial
keep-alives on RTP port
The number of keep-alives the phone should send out at the
beginning of an RTP session. A keep-alive is an empty
STUN Binding Request and serves to open a pin hole in the
firewall. The phone sends one keep-alive by default, i.e.
when the setting is empty. This is for backward compatibility.
Set this to zero if you want no keep-alives. Note that if the
phone receives such a Binding Request, it will answer it with
a Binding Response.
