Hi Guys,
Could someone just confirm my question about packet direction? Should it be
that packets go both from and to the phones or just one way?
Many Thanks,
Dave

Hi,
I have setup a server with the default config and my topology is as
follows:
192.168.10.2 (my PC with SJPhone)
192.168.10.20 (ZyXEL Prestige 2000W)
192.168.10.50 (IPTel SER 0.8.14 src)
Both phones register fine.
When I make a call all packets traverse fine ... phones ring ... I pick up
the phone and no sound.....
I know both phones work as I have had them running through asterisk without
issues.
Here is a tcpdump from my PC:
djs:/home/dave # tcpdump -n net 192.168.10.0/24
tcpdump: listening on eth0

No matter which phone I make the call from packets only go like above from
the ZyXEL to the SJPhone PC.
Am I right in thinking that packets should go both ways??
Any other ideas as to why I have no sound?
Pulling my hair out on this one :)
Cheers,
Dave
