In a outage, you must determine what is important to your endusers... If receiving calls are important, then a quick and dirty solution is to setup the Call Forward Unregistered Internal/External to users Cell Phones. When a site goes offline, the phone is considered unregistered from CUCM. Hopefully, CUCM is still reachable by your CUBE so this will enable the ability to receive calls to the locations that are currently experiencing an outage.   If you need the ability to dial out from the location, then you must have something local such as a gateway running SRST with some type of PSTN connectivity. Otherwise, you will need a VPN backup. Hope this helps... May not be exactly what your looking for, but it is a direction..  ... View more

Rodrigo, I'm not sure if you were able to resolve your problem, however I figured I would give you my two cents.  Graham has pretty much giving you some good suggestions.. I had a similar issue with Sonicwall, but mine was more of an issue with Expressway behind a Sonicwall.  The jabber clients had one-way audio.  I must have changed every possible SIP ALG setting in the sonic wall to correct my issue with NAT.  I was unable to find the right combination to make it successfully work.  Note, I was able to get this same setup to work fine behind an ASA without issue.  However, again "SIP INSPECTION" had to be turned on with the ASA for it to work. Now considering my issue was with Expressway, i was able to convince the customer to move the Expressway-E outside of the Sonicwall.  This ultimately solved my problem for this particular customer. The suggestion that Graham has mentioned with using a second interface and directly attaching the CUBE is a solution that we know will work without issue.   Just be sure to enable/configure the IOS firewall rules on the cube as well as lock it down to avoid any SIP Toll-Fraud attempts. thanks,  ...

Aaron, CAD is supported in 10.5.  It wasn't until 10.6 (10.5.2) that you could run both.  Here is a very good document that talks about the differences.. http://www.cisco.com/c/en/us/products/collateral/customer-collaboration/unified-contact-center-express/white-paper-c11-730883.html Note *UCCX 10.6 has some enhancements.  The document above was 10.5 and Prior.  See the attached release notes on 10.6. http://www.cisco.com/c/en/us/products/collateral/customer-collaboration/unified-contact-center-express/white-paper-c11-730883.html     ...

Ali,   CUCM does not have a way to password protect a meetme conference.  However, there are a few work arounds that you can do to accomplish this.  You can use Unity Connection or UCCX.  Unity connection will not prompt for a pin, but it will allow you to accept or deny entry into the conference. UCCX you can script it to allow for a pin.  Here is the Unity Connection way.   MeetMe number is 1111 and CTI RP is 2222   Create your meetme conf 1111 Creat a CTI RP with extension 2222 and CfwLL to voicemail Create the First Callhandler MeetMe-Transfer and under transfer rules: Select Strandard transfer Select Transfer Calls To: and enter 1111 Make sure to select Transfer with supervision Check: Ask Me If I Want to Take the CallAsk for Caller’s Name Create a Second CallHandler MeetMe-Welcome with 2222 extension and customize the greeting to say : Please press 1 to join the conference and under CallerInput make sure to transfer to the MeetMe-Tranfer. Look at this link for the UCCX Way https://supportforums.cisco.com/discussion/10777796/passwords-meet-me-conference   ... View more
