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. --- Bote FreeSWITCH Docs Janitor <http://freeswitch.org/confluence> http://freeswitch.org/confluence From: Varsha Agarwal Sent: Monday, 18 January, 2016 16:21 Subject: Re: [Freeswitch-users] Getting multicast paging to work I disabled ZRTP, but still not working.

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.
