Hello, I have some doubt about the compatibility from GPON system and IP video intercom . The IP video intercom use the multicast protocol to communicate from central unit to house unit, and vice versa, I know that the GPON system works with multicast protocol (we use an IPTV headend connected to the OLT and dedicated tvs connected to each ONU, and all work well), but when we try to connect an IP video intercom it work only when we disable the IGMP protocol in the OLT and the IGMP snooping in the ONU, and we don't know why.
Any idea?
