I know how to download (and thus save) messages, however, the phone system is for my mom and she likes to leave most of her messages saved so she can access them via the phone (Archive is limited to only 5 messages). She just recently had about 6 saved messages deleted (apparently due to expiry and tech supports attempts to un-delete them failed) however she claims there was no warning or information about how long a message can be retained... something I have also been unable to find in any documentation.
Can someone supply the specifics on storage time and what, if any, warning messages are announced when playing back messages, concerning remaining time until expiry (she is use to Telus's continuous "hit the ? key to re-save for ? many days" option).
