Beginner
I started working with Cisco as end customer in a companie that upgraded it's old Panasonic PBX with a Cisco Call Manager version 3.0 and IPCCX 3 back in 1994. By that time i had no idea about Cisco's telephony infrastructure so i had to learn about switches, gateways and IP Telephony. We had a lot of issues then at first while stabilization, but then it was very stable. In 1996 i decided to quit to find new challenges so I had the chance to start working in DESCA, a local Cisco Partner in Colombia. The new job forced me to study a lot, reason of that is that companie's objectives is to deliver high customer satisfaction based on the quality of services. by then i had no idea Cisco had so strong study career, with so many branches (Voice, R&S, Security) so i decided to learn Ip Telephony, of course after finishing CCNA certification, i continued studyng to achieve the CCVP certification. Since then i have being working with Cisco IP Telephony and Cisco IP Voice applications and services in different end customers and different projects, and now i'm looking for the Voice CCIE, a dream i think Engineers with experience like me have as well.

Hi, I want to share my experience since i already figured out how to solve it. On the following link: http://docwiki.cisco.com/wiki/Unified_Communications_VMware_Requirements Cisco is clear answering my question: Supported Versions, Patches and Updates of VMware vSphere ESXi ESXi Major/Minor Versions, Maintenance Versions and Patches/Updates Cisco Collaboration apps will explicitly indicate which Major/Minor versions they support (e.g. ESXi 4.0, 4.1, 5.0, 5.1, 5.5). There is no "or later" ... unlisted versions are not tested/supported. With a particular supported major/minor version (such as ESXi 5.1)... A Cisco Collaboration app will only specifiy a minimum maintenance release (e.g. 5.1 U1) if required by its guest OS or for hardware compatibility. A Cisco Collaboration app will only specify a MAXIMUM maintenance release if there are known incompatibilitites. To date this has never been the case, so if the hardware vendor supports it, it is allowed even if unlisted. Cisco recommendation is to use the latest Maintenance release supported by the hardware vendor. So i proceed to download the VMWare patch from 5.1.0 to 5.1U3 and successfully applied. now the customer is validating security vulnerabilities again to vmware patched version.

Hi Experts, Actually i'm woking on a BE6k installation and everything is ok but security on VMWare. Customer did a security analysis on all machinnes and found varoius vulnerabilities on VMWare ESXi 5.1, as the report says VMSA-2015-0001 ESXi Multiple Vulnerabilities, Man In The Middle SSL/TLS from Openssl, VMSA-2014-0002, VMSA-2014-0005, VMSA-2014-0006, VMSA-2014-0008, VMSA-2014-0012 among others. my question is, do i can download a regular VMWare patch upgrade and install it with no problems? or i need to search on cisco downloads any special cisco patch for vmware? anyone can help me finding the rigth way please? thanks.

Hi all, I have just configured two isr 39xx as cube and both in HA following the configuration guide in the following link http://www.cisco.com/en/US/products/sw/voicesw/ps5640/products_configuration_example09186a0080b40d82.shtml after configured everything works perfect, but customer want to use the second router DSP resources for transcoding while first router is active, my problem is that after i enable the HA with the redundancy inter-device the second isr dsp resources go unregistered, i wonder if this is the way it should work or if there is a possibility to utilize the second ISR DSP Resources while first router is active. i was able to chech the sccp configurations and the sccp protocol up and running on the second ISR but still not getting registered. thanks,

Hi Deren, Thanks for you answer, i have the node run ext script pointing to a VRU on CVP, the vru has the menu micro app. im invoking the VRU script name M,welcome (of course welcome.wav is the name of the wav file on CVP Server) and i'm adding the following configuration params " 1-2,Y,3,2" (up to 2 options to be dialed, y for accept default settings 3 seconds of interdigit and two repetitions of the prompt), but do you know if there are any option here to set a "none digits dialed" as the CED has on ICM? or which should be the best practice here? thanks.

Hi, Actually i'm recieving a call on CVP, the menu is played correctly and when the user dials 1 or 2 the call is routed to the correct option. The issue is that when customer does not dial any option the call is dropped. do you know if there is any way to route the call to a default option in case customer does not dial any number? i'm running packaged CCE 9 with CPV. thanks in advance

Hi, I'm working on a implementation of CPV with PCCE. At the moment i have set the configuration of CVP PSTN Gateway to recieve calls from PSTN and calls are working normally. call get routed to CVP and then to ICM and finally to the agent. The problem is that the call initially is answered by gateway with G711u, and then when the call is transferred to Agent, codec is not switched to G729, call still using G711u any idea why this behavior is? On the gateway i have set the voice class-codec to choose as first option the codec g729 and then as second g711, on the cucm agents are provisioned on the same device pool as cvp server, this config is set this way since im aware CVP Server does not negotiate media, but this negotiation is made directly from CVP Gateway. thanks in advance for the help.
