Hello Cisco Community, I wanted to get your advice with the configurations of a third-party SIP phone device in a CME environment. The problem I am encountering is that after configuring the "voice register pool" and " ephone - dn " for the SIP phone we are able to place calls and receive calls, but the calls from within our network are not able to connect. When a call is made from the third-party SIP phone and answered by any other phone unit in the network, the call does not connect and we listen to silence before the call is dropped. Now, placing a call from another VoIP unit in our network can establish and connect a call. Calling to outside the LAN we see no issues. We have the same third-party SIP phone in another LAN, but the other LAN has a CUCM in the mix, which makes it a lot easier to get it working. Any thoughts on what I could be doing wrong? Here is the config related to this unit in the CME... ephone - dn 164 octo -line number 464 name Conf Room Neo 2 voice register pool 5 id mac "device.MAC" number 1 dn 5 dtmf -relay sip-notify voice-class codec 1 username test1 password test1 voice class codec 1 codec preference 1 g711ulaw codec preference 2 g729r8 Thank you, - Gustavo ...

Hi Cisco Community, I wanted to get your feedback and recommendations on Layer 2 LAN extensions between two geographical Campus locations. My Manager wishes to use our LAN ASA to filter traffic in and out of this new geographical location. The only way I could think of this happening is to extend Layer 2 via MPLS. Of course, I have been reviewing the Cisco Layer 2 extension doc that is available out there in which provides lots of great details and information. I am more interested in the needed configurations for the ASA, and need your advise to get me into the right path. My assumption is that the majority of the configurations will be on the routing tables and not so much with the VLAN configurations on the site that has the ASA. The objective here is for all traffic in and out of this site to go through our ASA, which is remote, to the new LAN. I am still thinking that a ASA will be needed on the new location, since I am still looking a this from a physical perspective and not from a logical one. If I understand this correctly, the majority of the configurations between both sites will be concentrated on the routing tables and ACLs and not so much on the internal VTP configuration. Need some guidance as to where to focus my energy in my research and learning on how to get the remote site traffic filtered through a remote ASA prior to hitting the remote new site. Your help and guidance is extremely appreciated! Thanks, Gustavo ... View more

Hi Cisco Community, I am looking for some guidance on how to replace the SIP image and load a SCCP image into a Cisco 8945 phone. We have been reviewing the following link http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cuipph/8941_8945/firmware/9_2_2/english/release/notes/8941_8945_922.html#wp145767 with hopes of better understanding the problem we are encountering. We reviewed the "Installing Firmware Zip Files" section and performed the recommended steps, but, we are now encountering the following on image "Cisco8945Error" attached to this question. The phone currently has SIP image 9-4-2-8. Also during my quest for an answer on how to fix this, I have ran into this question in Cisco Support Community https://supportforums.cisco.com/discussion/11869586/i-can%C2%B4t-register-ip-phone-8941-cucm-cluster-803 in which I have read the following from Vadym Maliarov from Cisco... ""The Cisco IP Phone 8941 and 8945 support a new "secure by default" feature from 9.3(1) onwards, which requires devpack 8.0.3(24049)/8.5.1(14070)/8.6.2(22030) or higher installed on 8.x Cisco Unified Communications Manager before phones are upgraded to Firmware Release 9.3(2)SR1. If the correct devpack is not installed first, the phones cannot successfully register to the Cisco Unified Communications Manager!!! " http://www.cisco.com/web/software/282074289/103278/cmterm-8941_8945-sccp.9-3-2SR1-2-readme.html This is needed to support Security by default" If this is true, then how would I load the "devpack" into the phone? I am under the impression that this is already in the image file itself, therefore there should be no other file to load. Also, my counterpart when loading it through TFTP he changed the .zip file into a .tar file. I believe he will need to download the .zip file again and unzip the file to move each file into the TFTP. Your assistance will be greatly appreciated! Thank you! ... View more

Hello Cisco Community, I need your assistance on this action. I have recently received a DID pool of 99 numbers that I want to make available in our current CUCM. I believe there is not much configurations to be add/changed in order to accommodate this pool. I do not need step by step instructions, just some guidance as to what needs to be done first and the subsequent steps to get me to accomplish this task. I can review/read the configuration examples and other documentation from TAC. I am confused as to what needs to be done to add these. Do I start at the router or is just as simple as adding these through CUCM. Your recommendation is greatly appreciated. Thank you ... View more
