We run SIP phones (polycom 501s) to * and a tdm40b for PSTN out, mostly
SIP <-> PSTN calls but a few SIP <-> SIP calls. We haven't implemented
any vlans or QoS so from time to time the network traffic and latency
get the better of our communication. Usually this manifests as a slight
crackle, but when really bad, we get spaces of silence like you
describe. The user connected from the PSTN channel can hear us, but we
on the SIP phones can't hear the PSTN channel. sometimes for a second,
sometimes for 5 or so.
Have you eradicated any network latency issues you might have? Seems
like this could be the source of the silences for us. Also, it could
be our unmanaged switch flipping out I suppose. It's always been pretty
low traffic on our network.

I'm wondering if this could be related to the IAX peers becoming
unreachable?
Has anyone experienced moments of silence during a call, and do you know
what the causes might be?
