Hello, we’re are making a last-ditch effort to see if someone in the community has some advice on this problem as we are stumped and it’s looking like we will need additional equipment that we didn’t plan on getting yet. We have CUCM (V. 8.6.2.20000-2) operating in 2 buildings, connected with a VPN tunnel, and Cisco endpoint phones working for a while now. We are in the process of moving some of our users in our main building to Skype for Business, and all of our users in our 2nd building, which is where we are having the problem I am describing.
We have had our teams exhaustively troubleshot this, with help from Cisco, and are a bit stuck. If anyone has any suggestions, it would be greatly appreciated! I’m going to paste some of the Cisco 2811 current-config at the end of this post.
Thanks in advance for your time if you read this!
The main issue right now:
- Cisco 2811 Router FXO port no longer activates a Valcom V-2006a overhead paging system, when dialed through CUCM, both systems do not have official vendor support.
More details:
We use an overhead paging system for announcements (mainly fire drills/emergency notifications) in our 2nd building. On our legacy CUCM phones, we could dial a ## DTMF code, which dialed a gateway, to access this system. It’s now unusable, after making no changes, except implementation of an upgrade to SfB softphones for our users in that building and changes made to the Cisco 2811 router that activates that system which was backed out.
The CUCM system is tied in via a network connection to the Cisco 2811 router, in turn connected to an older Valcom V-2006a paging system, which requires a DTMF activation code of ##0 to activate the overhead paging speakers (tested, works with a test set phone hooked directly into it and dialing the DTMF code, but the 2811 router no longer activates it.)
We have had a lot of experts in the field working on this and they have come to some conclusions. Up until changes were made to our Cisco 2811 router recently for this project, this system had been tested within weeks and was working perfectly. Those changes were made by contracted experts in the field, with help from Cisco, but something went wrong and either there is a misconfiguration, or it was functioning as-is with an unknown problem for a while.
Up until now, the normal call flow of a call that activates our Cisco 2811 router’s FXO ports to dial the analog page system has looked like this:
[Phone/Endpoint] --> [CUCM SERVER] --> [MGCP GATEWAY] --> [VPN TUNNEL] --> Cisco 2811 Router FXO--> ##0 DTMF Dial which activates analog Valcom overhead paging system Our experts on this project, along with help from Cisco support, have come to this conclusion:
The reason for why this system was working up until changes to our Cisco 2811 router’s configuration were made is unknown, but since it is now out of support, we are looking at needing to replace the equipment since it’s no longer working. Cisco support has also apparently notated this is a bug in version CUCM 8.6 which we currently run.
They suggested the following 3 options:
- Restart our CUCM server, which we are going to do, tomorrow,
- Restart MGCP Gateways, which was done but did not help,
Or Upgrade to newer equipment compatible with a later version of CUCM, or an entirely different system that has support.
Here are their findings as to the problem with the call flow:
