RTCP active calls must be false if bypass is enabled and refer support is disabled Error

Reblog for your favorite post…

Ibrahim Soliman Blog

Issue:

In Lync Server 2010 While configuring a trunk to enable media bypass, and disable (un-enable) the refer support (as the recommended settings when creating a SIP trunk to Cisco Unified Communications Manager CUCM), you may receive the below error when you try to commit changes:

Cause:

A

Solution:

in the below example, my Trunk name is: PstnGateway:10.0.0.20

– in the trunk prosperities, Temporarily un-enable the media bypass, and commit to save changes:

– Now, let’s open Lync Management shell and check the status of RTCP Active Calls, and RTCP Calls on hold:

We see both are True by default, Also note the EnableSessionTimer status is False.

– Now, run the below commands to set RTCPActiveCalls and RTCPCallsonHold as false:

– Now lets check the status again:

Installing Cisco Call Manager For Non-Cisco Folks

Well, one day I built my OCS 2007 R2 Lab, and was very happy with it, except one thing… The Voice part!

The challenge was that after I configured the mediation server, I need to confirm it’s working fine and would interact with the IP GW/ IP PBX successfully.

After googling around and binging around, It worked for me -thanks God- and the virtualized Cisco Communications Manager (or Cisco unified Communications Manager Installation  CUCM) took its place in the lab, and configured to work with the mediation server.

In this article I will introduce to you how to setup Cisco Unified Call Manager on a virtual machine, and how to do simple post installation steps,But my guess is that you will use this not on your OCS 2007 R2 Lab, but in the Lync Server 2010 lab instead, right? Winking smile

Important Note: I ended the subject with: For Non-Cisco Folks” because my scope about installing, and configuring CUCM was for LAB purpose only, If you attend to implement this in production, you better consult a Cisco CUCM expert.

First: You will need:

– VMWare Workstation installed on your PC (I used version 7.x).

– Cisco unified Communications Manager Installation DVD (I Used Cisco unified Communications Manager  version 6.0.1.2000-4)

Installation:

Create a new virtual machine with these configurations:

  1. OS: RED HAT Enterprise Linux 3
  2. HDD: 80 GB
  3. RAM: 1 GB
  4. NIC: 1
  5. CD: Use CUCM6.iso
  6. Floppy: Remove floppy

Now start the VM, it should boot from the CUCM6 DVD,

Go with the installation as mentioned in the coming screenshots (Click on image to enlarge),

but note that, the mouse courser is for indication only, you need to use Tab/Space keys on your keyboard to navigate/select.

FAQ About New Microsoft Exams

There was some rumors about new Microsoft exams, so I decided to contact Microsoft training center to get the official answers, and I’d like to share them with you:
Q:
I was asking about TMG 2010 Exam,
The availability date?/ Exam Number?/ would it be for TMG 2010 only, or the exam will contain TMG 2010 and UAG 2010?

A: Unfortunately there is no available date or exam number for exams for TMG 2010 and UAG 2010. You will want to check back to the Learning Catalog for any updates for the TMG 2010 and UAG 2010.
I’m sorry we do not have any other information for you at this time.

 

Q:
in order to get my MCITP: EA certificate, I attended the 70-624 Exam:TS Deploying and Maintaining Windows Vista Client and 2007 Microsoft Office System Desktops
But as I see in your sites, This exam retired on October 31, 2010.
Would this affect my MCITP:EA? i.e. do I need to attend another exam to replace the retired 70-624 Exam?

A:
The retired 70-624 exam will not affect your MCITP certification. If you pass an exam before it expires, it will still could towards that certification.

Q:
Is there /will be a certificate about: MCITP: Enterprise Security Administrator or similar?

A:
Unfortunately at this time there are no MCITP certifications that fall in line with what you speak of. Please go to the following links to look over the types of certifications we offer: Certification by Product/Technology and Certification by Name. This should help give you an overview of what certifications are available to you.

Certutil -vroot

This might to be old but it’s neat

what happens when in windows 2003 you installed the Certificate Authority BEFORE you install the IIS?

Answer is : the \certsrv virtual directory will not be created in the IIS

Then, what to do?

Answer is open the command line and run:

Certutil -vroot

and that’s it, no need to uninstall and reinstall the CA.

Forefront Protection 2010 for Exchange Server Capacity Planning Tool

Download

Brief Description

The Forefront Protection 2010 for Exchange Server (FPE) capacity planning tool lets you understand the hardware requirements for planning new FPE deployments. It also lets you evaluate the system requirements for existing deployments.

Overview
The FPE capacity planning tool helps you understand how CPU utilization and memory requirements vary by specifying different protection settings of FPE. This tool is based on the capacity planning guidance provided for Exchange Server 2010. The FPE capacity planning tool uses two specific reference architectures, the Standard Reference Architecture which is targeted at the small to medium size customers and then the Enterprise Reference Architecture targeting larger organizations. You can select a workflow associated with a reference architecture and specify CPU utilization and maximum memory constraints for your targeted hardware. You can specify the desired protection settings for each of the FPE server roles in the associated reference architecture, and describe the desired environment to be supported. After all these items are specified, the tool produces a summary of the hardware requirements with the number of servers that should be utilized to support the targeted environment given the FPE protection settings and the specified hardware constraints. The tool also provides performance guidance using graphs to understand performance aspects of the product and comparative performance of virtualized and non-virtualized scenarios with different operating systems and Exchange versions.

System Requirements

* Supported Operating Systems:Windows 7;Windows Server 2003;Windows Server 2008 R2;Windows Vista;Windows XP
