We have a number of users at home using IP Communicator vpned into our network (Juniper client software). We continue to struggle with QOS issues (JITTER).
All users are using G729.
One of my users upgraded his bandwidth to 5mb down and 1 mb up (DSL). And he still has issues with his calls.
Looked over this document already.
Can anyone tell me what we can do to get a more permanent solution in place? Or ideas on what we can do to improve our current situation.
You probably want to take a look at this:
You can see that the Juniper VPN client isn't supported. This may or may not be a cause of the problem, but something you should be aware of.
If you have a router with QoS capabilities between the phone and the DSL connection, I would suggest shaping to 1 mb and putting the voice traffic in a priority queue. Getting something like an 871 to put there can give you more power on what type of traffic will get dropped/prioritized, but you can't guarantee anything over an internet link.
I would try running as few applications on the PC as possible and repeat the test. Turn off all web browsers, email, etc.
Try the Cisco VPN if possible
Get a QoS capable router to prioritize the traffic, mark everything properly.
