Upgrade CUCM 9.1 to 10.5 - Procedure (No Prime Collaboration Deployment)

So with the introduction of Cisco Prime Collaboration Deployment, now upgrade any of your UC applications its easier and quicker than before. One of the big advantages that I see with this new product is that the product can have control of the overall infrastructure, starting from VMware all the way to the UC applications. For a better understanding of this product you can use the following link: (http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/pcdadmin/10_0_1/CUCM_BK_U9C58CB1_00_pcd-administration-guide-1001.html) - The previous is the one for version 10.x – I don’t see too many changes from version to version.

SIP Devices unable to stablish PSTN calls

I was just reading the following Article and wanted to add few things that helped me solve my issue: http://uctickets.wordpress.com/2014/03/21/11-sip-9971-phone-unable-to-complete-pstn-calls/ *** bearer-cap speech *** This simple command also fixed an issue I had with Jabber clients calling from Softphone mode to cellphones, and they were getting straight to the voice mail of that particular cellphone. At first it looks like a simple issue with the phone company, but then you start re-thinking it because it happens with every cellphone you make and with every SIP device you have connected to CUCM.
