Hello everyone, we have deployed a CCM at our main office and are using out p2p T1 for connectivity to our warehouse. The phones work fine and all VLANs are communicating just fine. We are running a 2811 router with a NM-ESW-16 module to handle switching. We have also implimented an Informacast server by Berbee. The problem we are having is the Multicast configuration on the phone connected to the NM-ESW-16. They get the text but no audio. Any help is appreciated.
