Default Voice is breaking up

I have Linksys WRT54GP2 setup with SipPhone for over a year now, everything was fine up until just recently other party can hear me just fine but their voice is breaking-up at my end. It doesn't matter if the call is made from a PSTN line or Sip Phone in both cases their voice is breaking. No changes were made to the configuration or internet. Same setup for over a year. Any ideas what I should focus on????? thanks in advance

If your Linksys WRT54GP2 has a call status page look at 'Jitter' and 'Packets Lost' during a call.

Heavy Internet usage can cause VoIP to break up. Perhaps your neighbor is pirating your bandwidth, or mayby someone on the wired LAN is using bittorrent. Use WPA/WPA2 encryption with a strong shared key, or turn off the WiFi radio altogether.

This is my cousins VOIP in India. Wireless of turned off and at the time of the calls computer is also shutdown. Like I said it was all working for about a year and all of sudden without any changes it started to act up.

Were you able to get a reading for 'Jitter' and 'Packets Lost' ?

The problem may be a restriction in data rate at the ISP servicing the WRT54GP2. You may get some improvement by using a low rate codec. As a test, you should try the G729a codec setting and also set "Use Pref Codec Only:" to yes.
