I have seen this when Polycom has to communicate with none polycom
phones and a transfer is initiated to a polycom, unless the Polycom
presses Hold and then unhold, there is only one way audio, this is
without NAT involved. There might also be other cases when this
happens. My workaround is to add canreinvite=no

Hi,
Does any one experience that SIP phone to SIP phone (Polycom phone) calls
can't hear each other, but Monitor application records both end's voices. It
also happens in group pickup calls. Zap calls to queue (Local channel) also
experience this problem (sometimes, our SIP phone can't hear any voice from
incoming Zap calls when pickup, sometimes this happens after 10-50 seconds'
talk). It is weird.
