Daniel, I'm afraid I can't be of any help here; I had no time to investigate the problem and immediately switched back to 4.25. With 1 trunk connection (Aastra pbx to sipcall, 6 lines) my USG110 currently shows 24 open SIP sessions.

Hi Daniel I experienced the exact same behavior and changed back to 4.25. Any news if this problem was indeed solved with the new firmware? Thinking of switching from 4.25 to 4.32 now... Reto
