I’m am trying to setup Voice Notifications using the Atcom IP02 SIP device. I’ve read through the white paper explaining setup with IP01 and the few forum threads on this device but have hit a wall.
When testing an alarm I can see that the pipeline is active in Status/Alarm Pipelines but under Status/Voice Alarming pending calls remain 0. More so in Status/Logs I have the following 2 errors
Agent 06Apr2018 02:29:17 cannot find invite client transaction for call MxgDogeM-1523017756775@pemKaleoDesktop
CallManager 06Apr2018 02:29:16 Error state received from call manager. Reason: Not Found 
As for my setup I have both the voice notification and voice modules installed and gateway restarted after install. The Alarm Notification Profile for the IP02 is setup with user and password of the VoIP extension and the status is Registered with VOIP Host. I double checked the IP02 settings and that looks good based on other post and manual.
Has anyone ran into this issue or have any ideas on what I could test next?
