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?

perhaps you're missing your default route on the IP Office.

0.0.0.0
0.0.0.0
(Default Gateway)
LAN1

I have the deafult route set..


o.o.o.o
255.255.255.0
10.1.10.1
Lan 1

the sets work a percentage of the time but around 80% the caller states they can not here...I just noticed my SA time on one router is set to 3600...I will bump that up..maybe the router is dropping the VPN

hat route is not correct - as it will only apply to traffic being sent to 0.0.0.x IP addresses not any IP addresses.

Is this statement incorrect?

IP Address
The IP address to match for ongoing routing. Any packets meeting the IP Address and IP Mask settings are routed to the entry configured in the Destination field. When left blank then an IP Address of 255.255.255.255 (all) is used.

I am essentially leaving it blank? What address would I put there? The remote Ip phone or my remote VPN router ip?

Make your 255.255.255.0 to all 0.0.0.0

Ok. The customer has been on a 12 minute call no issue...It's an intermittent thing..hard to track down..once they are done I will make that change..

 

[Trems]

My mistake..it was set to

0.0.0.0.
255.255.255.255
10.1.10.1 (gateway)
lan1

0.0.0.0 / 255.255.255.255 ?

nice - real nice..... 1 IP address only.

[Trems]

I don't understand?

 

[hairlessupportmonkey]

think about it. all traffic - 0.0.0.0 with a subnet mask 255.255.255.255 might give you 1 subnet bit. just thinking about it no subnet bits. I cant get a subnet calculator to give me a result!

example - 0.0.0.0 / mask 255.255.255.0 is 0.0.0.255 right? being a class c subnet.

ok...I will change to
0.0.0.0.
0.0.0.0.
gateway
lan 1

When you set a mask of 255.255.255.255 you are stating that the ip address is a host so you essentially created a route for the host 0.0.0.0 which can't exist anyway. When you create a default route 0.0.0.0 w/ the mask 0.0.0.0 you are saying for any network look at this gateway.

ok, I have made the change to the default..i will let this run..

Thank you!

 

[Trems]

Still having issues...Default route is set. Customer still experiencing poor quality..Status showing Jitter over 40ms and Round trip delay over 390ms....any more ideas?

 

[Duffman88]

You can run a pathping to the other site to see where the bottleneck is.

What speed is your connection and do you have qos configured?

What codec are you using for the phones?

I am not an IT Expert so bare with me...We are using Netgear FVS338 routers at each end with a VPN set up between sites. using VPN policy and Ike Policy. The routers do not have QOS I do not believe. This is hookes over Time warner cable o0ne end is business class the other is home. Either way bandwidth should not be an issue. The phones are set to auto in the switch Most times I see them on G729 in status.

 

[Duffman88]

From a windows machine on the remote site go to start > run and type cmd and hit enter. Then type pathping 192.168.42.1 or whatever your ip office address is.

Your jitter and latency are pretty high so I am curious if we can find where that is coming from.

You can also run a speedtest.net on both connections to see how their speeds are.

What kind of traffic do you have running over this vpn on top of the voice?

[Trems]

ok I am not on site currently. I will try that.

I have nothing running on the VPN except 2 IP sets...

They have 2 windows PC's off the switch and 1 printer..that's it.

It makes no sense to me. Seeing it is a VPN and the VPN is solid I do not know what could be causing it..I am considering removing one router and using the tech tip 184 to install them utilizing the phone VPN...

 

[Duffman88]

It could be a problem with one of the connections, a virus on the machine causing network flooding issues. I have had bad printer network cards cause network issues. First well look at the connections and see what we find.
