Error: DSP timeout on event 6: DSP ID=0x2:

I have a cisco 1750 with two FXS voice card. There are many errors whick like "DSP timeout on event 6: DSP ID=0x2:" I can't make any calls to other router. I use IOS 12.1(5)T8. What is the problem ? Is it a IOS problem?

Sorry, the IOS should be 12.1(3)T.

As much as we recommend not using 12.1(3)T for voip (H323 or SIP) for the following field notice:

The 1750 platform in particular should not be affected. DSP timeout however has been a continuous problem in 12.1T series IOS. If you can please upgrade to latest 12.2 mainline, and reset the box (which you will do in process of upgrade) and examine the issue again, most likely the problem will be solved.

Hope this helps.

Thanks!

If there are some routers which use 12.1(5)T8. Is it need to upgrade to 12.2 mainline too?
