Avaya 5621 Issue

[Trems]

I have an IP 500 V 6.0.18 set up over a VPN with Netgear FVS338 switches on each end. running 2 5621 on the remote site. Callers complaining about not hearing person on IP set but IP set hears fine. I unchecked direct media path..no change.. any ideas?

I will say the customer says their computers are working fine even when the calls are inaudible.

I do only have one IP route set. I am not sure if that is all I need?

default route

0.0.0.0
0.0.0.0
10.1.10.1 (office gateway address Netgear FVS338)
Lan 1

Ip phones have static ip's on a seperate Ip...192.168.2.98 and 97 are the phones.. VPN set up between the two WAN addresses...

The route looks fine. You will notice latency and jitter on phones much more then you will on a computer. I believe the magic number for latency was less than 250ms and with jitter anything less than 100ms can be managed via a jitter buffer.

Do you have ip phones on both sites or digital at the main office and just 2 remote ip phones?

If you have ip on both sides id be curious to see how direct media path effects the calls. Try both on and off.

I have 5410 at main site. 2 remote 5621 sets...I had Direct media path selected..I turned that aff first as the original complaint was they could hear the caller perfect but could not be heard...I saw that was a possibility...but no change..

Since you have digital sets at the main office all communications goes through the IPO & VCM anyway.

Yes, It shows the calls on the VCM module in Status...

It is a routing issue.
The voice can not reach the ipo so there is something wrong from the phone to the ipo.
Use wireshark to see what happens to the voice packets.
