APRS-IS to RF messaging worked yesterday but stopped after toggling telemetry settings. Using APRX 2.8.1 on Raspberry Pi with proper digipeater configuration. Logs show messages reaching APRX but getting discarded with "History entry for sending call from APRSIS is too new". RF-to-RF messaging via digipeater still functions, as does RF-to-IS direction. Has anyone seen this timing issue with message history filtering? The viscous-delay and filter settings appear correct but something in the dupe-checking logic seems broken.

Update to latest APRX version as recent releases fixed several messaging problems. Check your filter configuration - using 't/m' filter alone may require area filter to prevent discard. The history timeout logic was adjusted in newer builds.

This is a known issue with APRX message timing. Try configuring the APRSIS source with 'relay-type 3rd-party' and proper msg-path settings. The dupe suppression algorithm can be overly aggressive if viscous-delay parameters aren't tuned for your local network conditions.

The old SMSGTE service has been shut down due to spam issues. If you're trying to bridge to SMS, the new SMS gateway requires registration of phone numbers to eliminate spam. This might affect your message routing if you had SMS bridging enabled.
