We are running intop an issue with our SX10 systems. Audio is fine when we are on video calls. However, when we use them to place an audio only call to the PSTN, the people on the PSTN side of the call complain of alot of echo and that the person on the SX10 side sounds distant. I don't see any issues with the media stream. The only difference I see is the codec 711 on the PSTN call and AAC on the video call. I am wondering if the ACC just does a better job with the sx10 hardware, acoustics of the room etc. Has anyone dealt with this? Any idea on how to deal with it? As an aside, we have put 8831's in the same room and there are no complaints when those are used. Have also tried an external mic with no real difference in quality. Chris ... View more

Working with a PIX running 6.1.3 and am trying to map tcp 7373 on an outside IP to telnet on an inside machine. I tried the following: static (inside,outside) tcp 216.26.172.212 7373 198.135.95.2 telnet netmask 255.255.255.255 0 0 conduit permit tcp host 216.26.172.212 eq 7373 any But for some reason this doesnt work.When I use the standard telnet port on both inside and outside it works fine. What am I missing here? ... View more

I have a mixed network of analog devices: ATA186's, 8274V's, 1700's with FXS's, and IAD's which interface with the PSTN via AS5300's. What is the best solution for faxing? So far I have worked with Fax passthrough, Modem passthrough, T.38, and cisco fax relay. I've had the best results with the cisco fax relay, but alas it does not work on the ata 186. The ata is limited to modem passthrough and "fax mode". "Fax mode" is not very reliable, particularly with multi page faxes and speeds above 9600 bps. So im looking at modem passthrough, which seems more reliable. My question is: Is modem passthough viable network wide? All of my devices support it, but is modem passthorugh designed for faxing? Any disadvantages? ... View more
