SIP Early Offer vs Delayed Offer

The most visited page in my blog is CUCM SIP Trunk to ITSP connection. From time to time my readers and students ask me to explain what the difference between the Early Offer and Delayed Offer in the SIP signaling is. Let's say your ITSP want you to use SIP signaling with Early Offer in the SIP Trunk. How can you be sure, that your SIP trunk really works in Early Offer mode?

CVP Scripting Part 1 (CVPS1) Course at Knowledge Club Slovakia

Many people, who work with Cisco UCCE/PCCE, ask me questions about developing IVR applications for  CVP VXML Server. These are so called Call Studio (or just Studio) Applications. In order to provide all the answers, several years ago I created my own developed CVP Scripting Part 1 (CVPS1) course. The course was presented by Knowledge Club Slovakia for CVP Admins in order to provide the additional information about developing VXML Call Studio projects. We will be happy to assist you, for your corporate customers or individuals who are interested in all CCE Solutions. And today I'm going to share some information about this training to you.

"The "value" attribute of the tag must contain a valid decimal or integer number" error in the CVP VXML Server

Hello to everyone! 

I haven't written anything on the blog for a long time. Sometimes there is no inspiration, sometimes just laziness 😕Today I wanna talk about the problem that I encountered while working with the Cisco CVP. One of my students was doing his lab and he complained that his Studio application for CVP VXML Server suddenly stopped updating when the changes were made. He tried to delete the script and re-deploy it, but the script simply could not be activated anymore. 

Cisco Unified Intelligence Center and CVP Reporting Server Integration Example

Greetings to everyone! I decided to write this post as a small addition to the Cisco DUIC course. This course discusses Cisco Unified Intelligence Center (CUIC), which provides reports for Cisco contact center products. The course describes the integration of CUIC and UCCE quite well, but there is a very small amount of information about how to configure CUIC for CVP reports. Let's discuss it now.

SSL Issue (CVP OAMP to Call Server Connection)

Recently, one of our customers complained to us about the "unusual" problem from his point of view, which he met in the Cisco Voice Portal (CVP). When he tried to save changes for the Call Server configuration, the Web Management Console (OAMP) returned the following error:

Call Server device with IP Address: <x.x.x.x> and Hostname: <server1> operation failed. Device could not be reached because of a failure in negotiating security certificates. Please refer to documentation for configuring security before trying the operation again.

CredSSP Encryption Oracle Remediation error when using RDP

When working with Cisco UCCE and its components, you often need to remotely connect to one or another system component via Remote Desktop Protocol (RDP). Sometimes the RDP session is not established, and the CredSSP Encryption Oracle Remediation error is issued. Let's see how it can be fixed.

Post Call Survey (UCCE+CVP), part 2

Good morning,

Let's continue the conversation about Post Call Survey feature, which was begun in the first part. It is time to discuss the VXML-application, which, in fact, plays all survey questions, as well as saves the responses received from the client. As usual, here are screenshots and, of course, I will give  necessary explanations to them.

Post Call Survey (UCCE+CVP), part 1

Hi everyone,

In this post I would like to talk about a topic that is asked by many of my students and readers, who deal with contact centers. It's about how to configure a Post Call Survey after a client's conversation with the contact center operator. Typically, such surveys are used for customer's feedback and evaluations about level of service for a contact center. The algorithm is usually as follows: a customer calls into the contact center, the operator answers. After the conversation ends and the operator is disconnected, the client is invited to answer a few survey questions and provide his feedback.  

Let's see now how to configure this functionality in the Cisco Unified Contact Center Enterprise, which is using Cisco Cutomer Voice Portal as IVR (VRU).

UCCE & CVP: Send To VRU Problem in ICM scripts

Yesterday I faced a fairly common problem that occurs when ICM scripts are created. This problem is very common in deployments where ICM integrates with CVP. When a call comes an ICM script and the script comes to Send To VRU node, it gets to an unsuccessful terminal of Send To VRU, i.e. in fact this node does not process correctly, and the caller hears either busy tone, or the system error message.
