Got a SG 200 Avaya router with client S/W for remote side P.C. running Phone Manager etc... No volume with softphone once connected. -1- 403 2.1.15, Got plenty of bandwidth for both sites, checked volume control on P.C. no problems all turned up, checked config in Phone Manager it's fine too. Can make & receive calls in and out bound just no volume. -2- Biggest pain is VPN dropping and re-connecting every 2-5 mins. Checked time limit set it to unlimited, same thing with data pass through. Call ISP no issues. Any ideas on one or both? Thanks.
 
IPAlot, it's not the delay as I have several different sites with the same set up and they are working fine. I this looks like it is timming out (vpn connection) and then re-authenticating almost like the line (ISP) dropped off. I monitered both connections during this failure and they were both fine. ?????? Thanks anyway.
 
Yeah, I am still inclined to go with the delay associated with VPN's regardless of the other sites. Whats the ping times from all sites?

what version of the vpn client are you using? I am using an sg200 also with some home users. I encountered this problem early on with the vpn client and got a "beta" version from our vendor that seemed to fix the problem. Since then I have gotten a newer version from the avaya website and it seems to work ok.
 
Also, IPAlot, what delay are you talking about that VPN creates? I'm curious, could you explain more about this "delay" and where it comes from?

Thank you in advance.
 
Well Stuzzy, when you want to do something it takes time, ie a delay. Nothing happens instantly, for example if you are at a bar talking to a lady she isnt gonna agree to go back to your place immediately, you need to work at it and this takes time (delay).

IPAlot/Stuzzy ping time was approx. 40mm when it would hit. I got in touch with Avaya support it seems that for one thing I was 3 S/W versions behind when received. Even though we did an upgrade to the latest release for the Sg200 it possed to still give out the same problem. The Avaya tech. couldn't stay logged in more than the average 2-5 mins. They have decided to ship a new one out to us as an advanced replacement. I'll keep you guys posted as I am curious to see myself, if it was D.O.A.
 
Personally I have a bad taste in my mouth about SG200's. The one and only I've worked with turned out to be a total dud. After wasting a month (!) fighting with it switched to multitech and Tahdah! instant joy.

However I have heard tell of them working well. Please update us when your new unit arrives, I'd like to know if you also got a dud or if it is something else.

After a few days of trouble shooting with my ISP Bell Canada in Ontario (Important for notes when working over here) and Avaya we figured out what the issue is. We received a new router SG200, same problem occurs. Did a remote ping test of our site, the signal drops exactly every 2 minutes and 36 seconds for over an hour of testing. What is happening our SG200 is sending LQR packets to our ISP. Our ISP recently upgraded their switches from Red Backs which supported LQR to new Layer 3 Junipper swithces which don't. SG200 as far as Avaya knows does not have the GUI ability to disable LQR. Other note is if you have an Alcatel 510 DSL Modem in routed mode the same problem occurs with LQR, if you're using Open BSD you can disable LQR). So far what I intend to do is log into my GNET Modem from the ISP and have it do the authentication to their Junipper switch in a PPOE Mode. Then I can change the SG200 to a static mode and won't need any LQR packets. If you're looking for other quick fixes Cisco keeps upto date pretty good with Carrier changes. Any one have any easier solutions, until Avaya can sort this one out?????????
 
Orlando, since you are in Ontario let me give you another heads up about Bell "upgrading" their stuff. I haven't been able to confirm this, but they are almost certainly upgrading the firmware load on their DMS CO switches, as I am seeing the same issue starting to appear in customer clusters in more and more areas. If you have a PRI provided on one of their DMS's, they are no longer providing inband audio for the busy signal. Instead, they are just sending a cause 17 disconnect signal and your PBX is expected to provide the audio. Easy to do on IP Office - in the system form, telephony tab, tick "local busy signal" and you're off to the races. Still waiting for an answer from my support channel on what to do for Magix/Legend.

You will know you have the problem if you call a busy phone number and get silence, then the call drops.

Hey Guys, Looks like everything worked out fine. Did as I said with the Modem letting it do the authentication in PPPOE mode. Then switching the SG200 to Static Mode. Internet traffic and VPN tunnels up and running fine.

P.S. Morrack, haven't expierenced the trouble yet but thanks for the tip. I'm sure that's going to save me a couple of days easy, if I had to be the founder of the trouble.
 
Question whats a SG200, is it a new VSU box ??

It's a VSU box with newer firmware in it, basically. Old name=VSU500, new name=SG200
