Hello!
Currently are networked H2020V1, H2030V1, as well as H3550V5. Uses standard networking Siemens H323 protocol.
Task - in addition to integrating H3550V8 in existing network. Configured all of the PBX, the calls work both ways. But by the time appears in the "Poltergeist" - by establishing contacts with H3550V8 no voice payload to the other side of the H3550V8 PBX. After some time again, everything is fine.
Questions:
1. Does it make to the networked H3kV8 Hipath2000V1? Is too much differences between versions, so that the HG cards are the differences?
2. Do a search problem over an IP network, providing a channel. Maybe that some of the necessary UDP RTP ports are blocked, which are required for voice.
Does someone have any idea which direction to look - ip channel PBX upgrade or something else?
Thanks in advance!
