Configure External Call Control

Table of Contents

To use External Call Control in Callisto, External Call Control must first be configured in CUCM.

Configure External Call Control Profile

Go to Call Routing > External Call Control Profile and add a new External Call Control Profile.

In the field Primary Web Service put the URL of the Callisto CURRI web service: http://callisto:80/curri/curri.asp .

Replace callisto with the respective IP address or domain name.

After setting up the External Call Control Profile, the trigger point needs to be set. At the trigger point, the UCM’s routing logic decides which route request is chosen.

In UCM versions 8.x and 9.x, the trigger point can only be set to the translation pattern. In version 10.0x and higher, two new trigger points are added: Route pattern and directory number.

Translation pattern as trigger point

Go to Call Routing > Translation Pattern and add a new translation pattern or configure an existing one.

In the External Call Control Profile field set the External Call Control Profile that is configured as described above.

Route pattern as trigger point

Go to Call Routing > Route/Hunt > Route Pattern and add a new route pattern or configure an existing one.

Set External Call Control Profile to the one that you created, as described above.

Directory number as trigger point

To use a directory number as a trigger point, go to Call Routing > Directory Number and set External Call Control Profile field to the one that you created, as described above.

It’s enough to set External Call Control Profile to the called number for External Call Control to work.

Announcement over External Call Control

To be able to play an announcement over the External Call Control, before a call gets put trough, you have to modify the SIP Trunk profile from the SIP Trunk, which is connected to the PSTN.
Go to your Cisco Administration web interface, then Device > Device Settings… > SIP Profile and choose the profile which is used by the Trunk connected to the PSTN. Head down to the paragraph Trunk Specific Configuration and set the parameter SIP Rel1XX Options to Send PRACK, if 1xx contains ‘SDP’.
