[Freeswitch-users] one-way audio problem on some inbound gateways, but not others (and no outbound gateways)

[Fraser Redmond]

Thanks David - it's more than one gateway though (different companies,
different countries), so unlikely that both changed things at around the
same time.

Because it was different gateways (and not all gateways), and different
softphones (in different locations), the only common denominator was
freeswitch.

Only one other thing is consistent: the gateway that works is geographically
close to our server (both in California), but the 2 gateways that don't work
are both overseas. Otherwise the only common link is Freeswitch.

Cheers,
Fraser
