The CUCMBE is ready to relate with PrivateServer using the SIP Trunk, but still it can't until we create the same configuration on the PrivateServer itself.

2.1 Prerequisites

If you came here then all the necessary prerequisites are matched.

2.2 PrivateServer configuration

You can refer to PrivateServer management documentation for creating a SIP Trunk. We are going to explain here which specific values need to be set up in order to create it properly.

In the fig. X you can watch a plain example of a working configuration. It's major differences from a standard one is that:


The Virtual phone number is optional and can be left blank.
After you're done with the Inbound you have to check that the Outbound section has either a dialing rule set to let the trunk be used or the trunk set as the default one.
