ladies and gentlemen who have VoIP knowledge, We are having a serious problem with our PRI line, when its plugged into the Catalyst E1 6608 blade, its losing its "D-channel" and dropping calls! We've now upgraded to CM 3.1(2c), we have all the latest firmware on the phones, gateway, it seems that all is working beautifully at night when we are testing, however, in the day when we start getting any sort of load on the system (more than a couple of calls) calls start dropping and we get this error in the log:
Error DchannelO OS- D channel out of service Reason[Optional]: 0 Explanation D channel has gone out of service When this happens we have no choice but to interrupt phone service for everyone by putting the PRI line back into the IOS Gateway, and it works fine .. details: WS-6006 version 6.2(2) WS-6608-E1 blade firmware 5.4(2) ON the 6608 blade: Port 3/1 Registered as E1 PRI Port 3/2 Registered MTP Port 3/3 Registered MTP Port 3/4 (Port Host Processor Not Online) - This could be the problem! however, we cannot get this port to do anything, i.e. disable, change vlans, nothing - it is currently in "enabled" state though! Port 3/5 Registered MTP Port 3/6 Registered MTP Port 3/7 Registered MTP Port 3/8 Registered MTP The overnight Error logs do not get this message, so i'm pretty sure it has something to do with activity on the line, causing it to lose its signal?? Does anyone have any clue about this? Any help is much, much appreciated ... thanks in advance! - jason Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=25742&t=25742 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
