There is some echo on LD PSTN calls when the two ends mistakenly talk over each other. I believe they have some VOX that attempts to enforce a ping-pong talk path (eg. the amps in one direction are always set for a gain of 0 while the other direction is a 1.0). Now the first thing that I noticed in making a PSTN call is that the remote side is very hard to hear. The gain between the Sipura-3000/PSTN and a Grandstream BT-100 is much less than between two BT-100's. I'm going to have to bump the gain up a bit in at least the PSTN->VOIP direction. Perhaps I need to do the VOIP->PSTN direction too. This is going to make echo even worse. -wolfgang -- Wolfgang S.
