FreeSWITCH can do the ping (configure a gateway with ping=true), but doesn't look at RTT.You might also be able to do it with sipp.I've implemented a SIP OPTIONS ping client in the past with a custom Perl script using Net::SIP and it'd be trivial to measure RTT, but no longer have the code. But it'd be quite simple to do. There'll be Python libraries for SIP out there too.On 10 September 2014 17:41, Alex Lake <alex@digitalmail.com> wrote:I want to get an idea of how well connected my fs boxes are to certain

The idea might be to send a SIP options packet to a remote address and
time how long it took to respond.
I suspect that fs can do something like this, but I was also wondering
if there exists an off-the-shelf Linux package (a bit like mrt) that can
do this. Failing that, some code in (say) PHP that can do it?
I would have some kind of scheduled job that would send out a SIP
options packet every 10s or so and keep track of the rtt.
