I am working with a customer to resolve an issue with voice quality and noticed something peculiar about the ATA-186 gateways- from the local network I am seeing 65-70ms response time to the gateway. Everything else is <10ms like I would expect. After a google search I see a few others mention the same issue. Is this an inherint problem with the ATA-186? Does anyone know of a workaround? In this situation adding that much delay on the LAN segment is pushing them over the edge on round trip time- hence the voice quality issues.
Thanks, I will give this a try. I'm also going to have the customer replace one of the ATA-186s with an IP phone. If the problem clears up then it proves we have a performance issue with the ATA itself...which is what I am expecting at this point.
Are you talking about just doing a ping to the ATA? If so from what I understand on these boxes the pings are given a very low processing priority so it does not act quickly on the ping. So it is not really network delay it is the processor lagging.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
