message feature 1 on m7324

[dublynr]

i have a 6.1 mics xc with a 4.1.5 nam. according to the book each phone can send a maximum of 4 messages to other phones with the exception of the phone associated with the cap module. it is supposed to be able to send up to thirty messages. i reset the cap module asignment for the 7324 and it lets me do 30 messages at atime. however after a few hours it goes back to only being allowed to sent 4 message and then displays list full. i did not have this problem on mics xc1.1. help greatly appreciated.
