Perhaps you are being led astray by the term “multicast group” in the usage prototype. That is simply the multicast address, such as 239.1.1.1 FIXED! IGMP = Internet Group Management Protocol which is where that came from. I have used mod_esf to send multicast streams to devices manufactured by one of my clients and it worked swimmingly with only the multicast address and port being the fields that mattered. Thanks to a change by anthm you can even add it to the conference bridge if you want both regular SIP calls and pages to be combined into one group announcement. With a phone there’s no telling what else they might require to light it up for a multicast announcement. Somebody was just asking a very similar question here last week for a different phone. If the phone requires some control signal or command to open up the speaker for a multicast announcement to follow, then I don’t think FS does that right now. It might be worth scouring Polycom documentation to see if they reveal any secrets. * * * I really wish the order of the arguments were Address, port, TTL, [other stuff] So that “other stuff” could’ve been made optional. I have never gotten a clear definition of what that Linksys control port does, but my research revealed that it was likely carried over from an Asterisk compatibility feature. --- Bote FreeSWITCH Docs Janitor <http://freeswitch.org/confluence> http://freeswitch.org/confluence From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Peter Hartmann Sent: Wednesday, 27 January, 2016 22:27 To: FreeSWITCH Users Help Subject: Re: [Freeswitch-users] mod_esf with polycom Thanks Brian. Yes, I've tried it. It looks promising though, since I can see some of the default polycom settings defined in variables. Nothing about group is mentioned...so maybe it's going to the default group? I have a feeling I'll be doing a packet capture on a group-25 (emergency) broadcast to see what it does.

The source suggests that it's supported, but the arguments in the documentation seem specific to Linksys. From using the feature directly from a handset, I imagine we have to pass multicast-address, multicast-port and group-number. I've tried every combination and permutation with no luck. The reason I'm doing this is because if the emergency group number is used, the announcements will be at full volume regardless of the hands-free volume setting. And also I'm looking to do this in FS because I'm bridging in another PA system also.
