nseto, You were exactly on the right track. The Grandstream PSTN gateway had a silence timeout on phone calls set to 60 seconds. Incoming calls on hold or parked (no hold music) were being disconnected by the gateway causing the phones to lose the call. Outgoing calls were being disconnected when people were on silent hold for people they dialed. I very much appreciate your helping point me the right way in approaching this issue.

The issue has seemingly worsened, and it does appear the SPA525G2 + 500S phones are saying BYE to active calls. Now the issue is occuring when users making outgoing calls and when incoming calls are even muted. Is there anyone who's seen this behavior on these SPA phones? Or tell me where I should look next? Thanks very much, Nathan Envision IT, LLC ... View more

Nseto, Here's a log of an incoming call that was parked and subsequently disconnected before anyone had the chance to pick it up. Let me know if you need more of the debug log. Thanks!

nseto, Thank you so much for the response, and I'm sorry for the delay in answering. I have all the options for debug set on the receptionist SPA525G2 with a 500S attendant console. I'll post the contents of a disconnected hold / parked call as soon as we have another confirmed. Thanks again, Nathan Envision IT, LLC ... View more
