Last night, we ported over our DID's from legacy ISDN/PRI to SIP trunks from PSTN. After doing so, our conference bridge from UCM to Lync will not connect. I suspect an incompatibility with the SIP trunks or profiles but cannot determine the cause. I am able to dial the internal route pattern to reach Lync successfully, but cannot connect from outside our cluster. Previous call flow: PSTN>PRI>RouterH323>RoutePattern>SIPTrunk>LyncServer Current call flow: PSTN>TelcoSIPTrunk>CUBE>SIPTrunk>RoutePattern>SIPTrunk>LyncServer   I see the call trying to connect in debugs but it never gets past the connecting status.    Any suggestions?  ...

I recently configured an 8851 phone to connect to an ASA using Anyconnect and a VPN profile in CUCM (11.5).   I was relieved to get this working but was a bit alarmed that when the phone registered off site, I was not prompted to enter a password.  I understand there is an option in the VPN profile on CUCM for authentication mode, with options for certificate, password only or username/password.  I have a couple of questions:   1.  If I enable the username/password, what credentials are used?  Do I need to assign the phone an owner and/or associate and end user with the phone?  We are AD integrated on CUCM.   2.  If I enable username/password authentication mode, is the phone-vpn-trust cert still utilized within the ITL file on the phone?   Thanks ...

CUCM 11.5 with 8851 phones.   I have been asked if it is possible to create a service or similar to initiate a text.   Use case scenario:  Receptionist has an unwelcome visitor etc.  Rather than picking up the phone and dailing 911 or other number, we would like a way to discretely push a button on her phone which will then send an email or text with a pre-determined message. Is this possible with a service button?  If not, any third party apps that may work for this application?   Thanks ... View more

Running UCM 11.5, LDAP integrated with AD.   I have a handful of end users who have access to PhoneAdministration permissions group so that they can add/modify/delete phones etc.  Works fine.   I tried to add the same roles/privileges to another user and they are unable to login to ccmadmin page.  They are able to login to ccmuser page so I know it is not a password issue.  I re-synched LDAP to no avail.   I compared this to known working users and she is identical.  I am baffled as this is a simple change that is not working.   Any other troubleshooting steps or ideas to consider?   Thanks. ...

I am in the process or replacing three EOL 3800 voice gateways (H323) with 2911.  I am having issues with one location and curious on feedback.   I replaced the router 2 weeks ago.  Everything was fine until earlier this week.  The circuit went hard down from the routers perspective, seeing remote alarm and the controller was down.  Initially I thought it was a carrier issue so I initiated a ticket with them.  They were able to test clear to their NIU (I know....we have all heard this before...) and tossed it back to me.  I went on site and unplugged the cable, put in a loop back, plugged it back in and it came up.   Hmm, I guess it just needed to be reset?   Well, As soon as I left, the circuit went down again.  This time, I logged and verified the controller was down/remote alarm then did a shut/no shut on the controller and voice port and it came back up for 15 minutes or so.  I limped by monitoring this for most of the day while I continued to troubleshoot.   Fortunately, I left the EOL 3800 configured and racked directly next to the 2911 so I connected with 3800 with the same cables and monitored for an hour with no issues.  As soon as I move everything back to the 2911, the controller takes a dive after a few calls.  Unable to take anymore outages, I moved back to the 3800 and all is well for 24hrs.   During the troubleshooting process, I saw a few bugs that could be somewhat similar to my issue so I upgraded which did not help.  I opened a TAC case but the engineer advised that it is a line issue and using the 3800 is not a valid test to rule out hardware/software issues on the 2911.  The configuration is identical on both.  The cabling is the same.  They are sitting right next to each other.  He asked that I tweek the cablelenght settings on the controller, but I have already had enough outages that I cannot afford to try various lenght settings.   So....I am leaning towards pushing for an RMA on both the chassis and the hwic card.  This is actually the second card I have used on this router.  The first one was out of box failure, as soon as it was connected to the router, the controller would take hundreds of errors within seconds and would never establish a connection so was RMA'd under a different case.  TAC is pushing back on the RMA.   Any advice here?  Running c2900-universalk9-mz.SPA.154-3.M8, the same code I am running at a few other locations with no issues.   Thanks for any input ...
