We have Tardnberg MXP end points at 2 sites in the UK and 1 in China which all work well. We are now experimenting with certain remote users have home video conferencing using Polycom PVX. The users are using standard home DSL lines.
By modifying the settings on their DSL routers I can dial out from the Tandberg to the users machines ok but I cant get them to dial in. Sometimes the call connects but with no video or sound. Othertimes it won't ring or connect at all.
I assumed it was a Firewall issue in our offices however at one site there is no firewall. I also took a laptop running PVX and connected it to the same connection as the Tandberg and it connected ok so it seems to be a compatability issue. I've checked all ports and settings and just can't see anything. Does anyone have any ideas?
