I have a customer where we recently installed CUCM 184.108.40.2064-1. I'm sure it worked before, but could be wrong. Once one goes to User preferences, rings, default ring. it give me a message Ring List Unavailable!. I have allready loaded the latest available devpack "cmterm-devicepack220.127.116.111-1.cop.sgn", without any luck. The customer has all 7945 phones. The strange thing is that when I use mu Cisco IP Communicator on the same cluster, I don't have any issue. Any suggestions?
Hello, I was hoping for a follow up on this thread.
CM version: 18.104.22.1680-13, installed devicepack-22.214.171.1241-1.cop.sgn almost a week ago. It was brought to my attention today that the only ring tone availabe on a 7921 is 'Chirp 1', further investigation shows no available ring tones on a 7920, and intermittent issues on 7940 including error message 'Ring List Unavailable...'.
Java, I went to TFTP File Management, did search for 'ringlist.xml' which returned nothing. So what now, what would've have happened with the dev pack upgrade? Any assistance would be appreciated. I've also opened a TAC case.
this is a bug, which happens since version 3.x .... yes ... 3.x
anyway, what happens is that TFTP cache some files into the memory, even restarting the TFTP service does not clean such cached files from RAM. maybe restarting the server (since that will clean the memory and make the file get cached again).
apparently TFTP cache some files to make it promptly available to phones, this is useful when you have a massive firmware upgrade for example and you have several phones requesting the firmware (.bin files). if the file is cached the server does not need to read such files from disk but it does from the cached file on RAM memory instead, as we all know RAM is much faster than disks.
what happens is that ringlist.xml is one of those files.
my case i went from version 8.5 to 11.5, here is how i fixed.
1 - got all the files from 8.5 (ringlist.xml, DistinctiveRingList.xml and all files with the .raw extensions)
2 - uploaded all files manually to the new CUCM (version 11.5) by going to OS admin >> software upgrade > tftp file management >> upload.
3 - go back do CUCM admin, into service parameters >> Cisco TFTP >> advanced and change "Enable Caching of Constant and Bin Files at Startup " to FALSE
4 - restart TFTP
5 - Restart the phones.
6 - check if the issue is fixed
7 - go back to the service parameters and change " Enable Caching of Constant and Bin Files at Startup " back to TRUE.
I'm not able to access my old voice mail messages all of a sudden. The recording says something like 'the message is currently not available'. This has never happened before in all the years I have been using this system. I have t...
If you have 2 ISR routers, one acting as Failover, do we need to have both the same number of SRST licenses on the 2 routers?
No. You will only need the SRST licenses on the primary router. Because this feature...
