U2980/U2990 Disconnected from the CTI

Publication Date:  2015-06-30 Views:  298 Downloads:  0
Issue Description
After the DSP MEMLNK command is executed on the unified gateway, CTI connect status is not Connect in the command output.
Handling Process
1. Verify that the unified gateway can communicate with the CTI-Link.
Ping the CTI-Link from the unified gateway. If the CTI-Link cannot be pinged, check the network.
2. Verify that the CTI-Link IP address is correctly configured on the unified gateway.
LST MEMLNK:;
If the CTI-Link IP address is incorrect, run the MOD MEMLNK command to change it.
3. Verify that the network port actually used by the GPU/SGU board is the same as that configured.
If the U2980 uses the one-line access mode, the IFM module on the GPU board communicates with other components through the SMU board. In this case, you do not need to connect a network cable to the GPU board and therefore can skip this step. In other cases, run the DSP PORT command to verify that the network port used by the GPU/SGU board is correct. For the detailed port information, see the CDE online help.
4. Verify that the unified gateway information is correctly configured on the CTI-Link. For details about how to configure data on the CTI-Link, see CTI-Link Configuration.
5. Verify that the IP address of the unified gateway does not conflict with IP addresses of other components.
If the conflict exists, change the unified gateway IP address to be a unique one.
6. Verify that the Intelligent Service System (INtess) version on the CTI server matches the unified gateway version.

The CTI-Link connects the unified gateway to the CCS using the INtess, so the INtess version must be correct. If an incorrect version is used, the unified gateway cannot communicate with the CTI platform.
a. Log in to the CTI server as the CTI installation user.
b. Check the INtess version.
chkCTI -fileversion | grep ctiserver
/home/icd/icddir/bin/ctiserver  eSpace CTI V300R005C50SPC002 for VIDEO  31813949   2013-04-19 11:31:24  2013-02-25 15:51:06
− If the command output contains "for VIDEO," the INtess version is "INTESS5," which matches only the U2980 and U2990.
− If the command output does not contain "for VIDEO," the INtess version is "INTESS3," which matches only the UAP3300.
If the INtess version does not match the unified gateway version, reinstall the CTI or replace the INtess version. Here, the INtess version (INtess5) replacement method is used as an example.
a. Obtain ctiserver_video.tar.gz in the CTI installation package and upload it to the CTI Server as the icd user.
b. Log in to the CTI Server.
c. Stop the CTI Server service.
d. Back up the CTI Server process file.
mv /home/icd/icddir/bin/ctiserver /home/icd/icddir/bin/ctiserver_uap
e. Decompress ctiserver_video.tar.gz.
tar zxvf /home/icd/ctiserver_video.tar.gz
f. Replace the CTI Server process file.
cp /home/icd/bin/ctiserver /home/icd/icddir/bin
g. Restart the CTI Server service.
7. If the fault still persists, obtain help through the channels described in Help Channels.
Root Cause
 The unified gateway cannot communicate with the CTI-Link.
 The CTI-Link IP address is incorrectly configured on the unified gateway.
 The network port of the GPU/SGU board is incorrectly configured on the unified gateway.
 The IP address and module number of the unified gateway are incorrectly configured on the CTI-Link.
 The CTI-Link status keeps switching between active and standby.
 The INtess version used on the CTI Server is incorrect.
