SIP Trunking Dropping Calls at 16:05

[Cat5Jive]

Hi all,

Having an interesting experience with an IP Office on the most recent version of 9.0. SIP calls work fine but will disconnect at 16 minutes 5 seconds every time. The issue occurs on both inbound and outbound calls. Interestingly enough, the external call gets disconnected but according to the desk phone and the SSA the call is still connected, even though the external call party has been disconnected. Any tips?

Thanks!

In the absence of networking issues, check the session refresh interval offered on incoming calls from your provider. There's a setting in IPO to use "On Demand" to match up with the far end.
