IP Softphone problem

[TheDoz]

Hello everybody,
Installed softphone on my home network. On my laptop, I can call an ip phone both transmitt and receive sounds great when talking. When I talk to a digital set transmitt sounds great but receive sounds choppy(cuts in and out). This happens when wireless or hard wired to the network.
Any ideas?
Thanks

Are you hard set to an IP codec on the softphone. If you have the compression set to auto it will try to use 729 first. Try setting it to 711 and see if it is better

Thanks for the reply,
I'm going to load softphone on my other computers and try diferent settings to isolate problem. I will get back to this post later after a little more testing.
Thanks again.

Are you using a VPN tunnel

Have you uninstalled the Microsoft Qos protocol?

Take Care

If at first you don't succeed, skydiving is not for you.

Matt Knight,
Not using VPN, this is at my house home network only.
I have not uninstalled the Microsoft QOS Protocol.
Do I need to uninstall that?

There wass an issue with the default MS QoS on windows XP SP2.

Here is the tech tip, but I don't think it applies...

IP Office Technical Tip (Region: Global)
088: Windows XP SP2 PPTP VPN Clients and IP Office Phone Manager Pro

19th August 2005 - Full PDF Text Version



An issue has been noted when using VPN clients on Windows XP SP2 PCs. When directly connecting to a network without using VPN, both XP SP2 and XP SP1 work as expected.

However, when connecting to the network via VPN using a PPTP Windows client on Windows XP SP2 and 3.0(13) Phone Manager Pro, there is an issue with the quality of the audio path in one direction. The Phone Manager user connected via VPN to the customer’s network hears excellent voice quality. The other user hears an intermittently distorted audio path.

This problem does not occur when using Windows XP SP1.

In order to resolve this issue, the quality of service (QoS) packet scheduler on the XP SP2 PC must be uninstalled. Simply disabling the QoS packet scheduler does not resolve this issue.

To uninstall the packet scheduler, right click on ‘My Network Places’, and select properties. Select the network connection in question, then right click and select properties. Highlight the QoS Packet Scheduler and select the uninstall option.

Take Care

Matt,
I uninstalled the QOS protocol, still no change to the problem.
I've tried serveral options and still have same problem.
Still testing, when I get a chance. Thanks for feed back on this.
