SIP Trunk Config

The following describes the IP Office configuration required to route calls to a CS1K (with NRS) via SIP. This example was built between a CS1K 5.5 and IP Office 8.1, and functions well. The configuration is fairly standard, and should work for other releases.

IP Office SIP Trunk to CS1K

The following key settings are used in this example:

In the CS1K NRS, the IP Office is added as a "Static SIP Endpoint", with "Name: Mikes_PBX", and "IP address:".
CS1K NRS Routing entries must be added to route CS1K calls to the IP Office, and this is not covered here.

You can also download this configuration , and edit the IP addresses and domain names (within Manager) for your application.

The IP Office network must be reachable from the CS1K TLAN, and visa-versa. Confirm this with some Ping tests.
