Hi all, Does anyone know of a method of sending a raw G711 stream to an address in Asterisk. For example, an application that takes a argument of a phone and a port. The reason? I have found a method to paging on Zultys ZIP2 and ZIP4x4 handsets. Basically it involves sending a stream of RTP data to port 3771 to multicast address 224.0.0.1. Would it need to involve me writing my own application for asterisk? Thanks Mathew -------------- next part -------------- An HTML attachment was scrubbed...

As far as I am aware there isn't a way for * to receive/send audio to a multicast group. There needs to be a way for Asterisk to tell the phone which ip multicast group to join in order to receive the page. This method varies by vendor. I know that with Cisco ip phone multicast paging they send a SCCP message to the phone to instruct it to send the appropriate IGMP join for the multicast group. Another way would be to advertise the ip multicast groups with SDP. Do you know how the Zultys phone knows which ip multicast group to join? I hope they aren't statically tying themselves to 224.0.0.1 as this is a reserved ip multicast address always has a TTL of 1. If they are using this address have them read RFC 1112.>>>The reason?
