[Freeswitch-users] Getting multicast paging to work

I'm pretty sure that esf_page only sends out PCMU in the clear, I doubt it
does ZRTP or anything else. It's a pretty basic app.
I have used it in a recent build of FS and it worked then, perhaps 3 months
ago. Not every phone responds predictably, notably Cisco/Linksys phones
which apparently use a proprietary protocol from their own pbx to light up
the phone on pages.
It's a one-way protocol, it just blasts out RTP packets via i.p. multicast
so there's no negotiation to be done.

I disabled ZRTP, but still not working. It looks like mod_esf does not do
anything... This is the last thing I see in the log

Are the pbx and phone on the same subnet?

Hi All,
I am trying to get multicast paging to work with the default configuration
in FreeSwitch. I am using 239.192.0.2 multicast IP Adress on port 8000. I
have configured a phone with that multicast address and phone, however when
I try to page, I just get dead air. I see some ZRTP negotiation failures in
Freeswitch logs. Can someone tell me what could be wrong
