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?

 

Thanks,

Subject: [Freeswitch-users] Getting multicast paging to work

 

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
