SPA122 crashes daily, how to disable unwanted services?

[jenomarton]

My newly purchased SPA122 ATA with router crashes regularly, (daily) , no dial tone, no internet going through.

Only power on/off gets it working again !

Using the latest 1.2.1 (004) 2012 Summer firmware.

Many post mentioned, that disabling many unwanted services might help.

Can somebody advise, what  exactly to disable, how  and where?   

Thanks !

Take a look at the thread above.  It seems like this is an issue caused when the customer receives a voicemail (or more likely, MWI).  It also sounds like there's a potential fix, firmware 1.3.0.

I have customers experiencing this same issue so I'm going to try to get hold of this firmware from Cisco.
