Howdy, Maybe the clipping of your SIP packet is occurring on another provider's (faulty) node somewhere in between your dualing pcaps at the endpoints ? As for what you can control, first, you might try reducing the expiration from 3600 to 999, or maybe something in the 30-60 range is better for you. If that works, then raise it from there, but I think an hour is more than enough. Or, change network paths; by adding new outbound SIP connection to the provider from alternate port and/or IP on the PBX/firewall, use VPN, etc. Regards, -- 🤠 C.
