Issue Description

Device: MCU 8620 by IP networking
Version: train 1
Concatenation device: MCU MGC50
Phenomenon: concatenation failed

Alarm Information

GK log inform: GK reject unauthorized call

Handling Process

There are two ways to do concatenation according to RMCC version:
The normal version:
1,Amend GK configuration files gkcfg.ini
#gk is reset and whether reject unauthorized call: 0 not reject;1 reject
drop_call_after_forcedrestart=0
[CALL_SETTING]
# whether enable call the IP
enable callipaddress=1
Reset SwitchCentre to take effect
2,Add a terminal number to MGC50 to RMCC, for example:010001, and set a password  1
3,Set the number on GK,MGC50 can not login by it, because the MGC50 can not fill in the password
4,Amend GKM configuration file gkmcfg.ini:
## The number allocating mode:1--SIP interface; 2--RMCC; 3--SwitchManager local UI (default).
OPEN_ACCOUNT_MODE=3
Change the way to set number to local interface, rest the SwitchManager service.
5,Change the way to authorize MGC50’ 010001 on GKM to IP address authorization. The IP address is new on MGC50 board.
6,After MGC50 logging in GK, make a conference on RMCC with the MGC50’ 010001, if we need multi-image, we need to amend RMCC configuration flie rmcc.ini;
MCU_Type_Of_PSTN=1; 4 menu mode-(1: standard, 2,non-standard,3, non-H.264, non-H.263  4CIF) use the standard multi image
7,Make a meeting with 8620 MIPU on MGC50 and turn on the speed adaptation.
8,Add the MCU of each other to the conference and finish the concatenation.
The RMCC version(with other factory), it can use IP address on RMCC directly as follow:
1,Amend GK configuration file gkcfg.ini(as same as normal version above)
2,Make a meeting on MGC50(without MCU MGC50)
3,Make a meeting on MGC50 with 8620 MIPU meeting site
4,Right-click activity meeting on RMCC, choose add meeting, input the IP address of MGC50.

Root Cause

A 8620 conference site is added to MGC50 with the one of the MIPU board IP. As all the 8620’s MIPU board are logged on GK, when a node setup to MIPU, the MIPU will send GK ARQ to test whether this is a unauthorized call. The MGC50 is not logged on GK, so it is rejected.

Suggestions

Choose which way to concatenation base on the version of RMCC and turn on the speed match function. After concatenation, the MGC50 is as a meeting site, so if the terminal on 8620 want to see terminal B on MGC50, firstly, we need let 8620 on MGC see terminal B, then let A on RMCC see MGC50.
