COMREX STAC-VIP and VH2

As of June 2018, OnSIP has been advised that Comrex has discontinued the STAC VIP.  It will still register with OnSIP but may have limited support from Comrex.

 

To configure a Comrex STAC-VIP system to use OnSIP, follow the steps below.

First, go to "Line Configuration" in the configuration interface. 

Then click on "Add Provider".

 

Under "SIP Provider," choose "OnSIP".

In "Account Information", enter the OnSIP username in the "User Name" field. Also enter the OnSIP proxy in the "Proxy/Domain" field.

Enter the OnSIP SIP Password in the "Account Password" field.

Save the settings and check in admin.onsip.com under the user (after refreshing the page) to see if there is a registration.
