Is anyone experienced with setting up QOS or Bandwidth Management on Sonicwall's Enhanced OS? We're trying to fix a problem with a site using remote VOIP phones. We've been able to affect the problem, but only one way. It seems that Bandwidth Management is having the most affect, but we can't seem to balance it to correct the issue in both directions. In other words, we can get rid of the jitter on inbound voice, but not on outgoing voice (or reverse).

If someone is experienced in setting up QOS or Bandwidth Management on Enhanced OS (hopefully as it relates to VOIP), I'd like to find out the best way to set it up.

Thanks!

Which codec are you using? Try using G.729. Remember you are only as good as your weakest link when you traverse a public network. Are you using AES-256 or 3DES?

I don't remember what ESI uses, but it's not something that can be changed. They have a proprietary way of making their IP phones work. When they have a good connection they work just great.

As far as the encryption, I'm not sure, but we're not going thru their VPN, as it adds overhead.

Is it possible to bypass the VPN switch or turn off any firewall scanning on the VOIP packets?

Have you tried contacting the sonicwall tech support?

You know, I'm very glad that I did not pay extra for the sonicwall tech support.

They have actually now outsource their tech support to an offshore Indian Call center using a very low quality voip line which can hardly be heard with Indians which can hardly speak a word of English and just reads a script with little or no knowledge of the product!

I can't believe sonicwall has the nerve to charge anything for the tech support which I would consider that the worst tech support I have ever seen(even if it was free)

I was wondering if anyone else has had this experience with them.

YES!

There are a couple of ways around it though. If you go through the online Sonicwall training and get certified, then you can go straight to Level II support. The other way is call India and don't tell them anything! Just give them the absolutely necessary info to open an ticket and get the ticket number from them. Then tell them that you're having issues and will have to call back. Then call your sales rep or channel account manager. Give them the ticket number, and have them escalate it to Level III out of Arizona. If the Level III tech's name is Al Carp, ask for another engineer. Trust me on that one. :shhh:

Yes, but when we tried that, we NEVER got a call back! And this was on a service-affecting issue!

Never had that problem Justin. Once we got our channel acct. rep to escalate it, we've always been good to go. I will say though that it has been our experience in the past though, that if we can't solve it in house, Level III doesn't stand a chance of helping though. On the last issue, we had a ticket open for 90 days of them working on it. We finally called a tech meeting on a Saturday to work on the problem and we did solve it. The VP over tech support felt so bad that our account manager got him to upgrade all our units at no charge to keep us as clients.
