On Users Guide that came with my new set ofCS5129-5 phones, there are instructions on accompanying large sheet on how to set the # of rings for incoming calls. I understand such information. I have done everything shown to be done, but the number of rings that I want to use (which is 6) will not save. Already spent six hours trying, and now I'm highly pissed. am grtCS pissed User's recommendation: Can't recommend.
