Issue Description

customer confirmed that he can not make outgoing calls from his U1960 PBX

Handling Process

first of all we checked the version and it was v200r003 

second we asked him if it is a new installation and he said yes

we tried to make calls while capturng the logs from the LMT as per below steps 

1- Choose Log Management > Call Log

2- click on  Module Switch Configuration

3- then after that choose the below parameters 

After that we found that the peer side is returning 487 request terminate to our U1960 

Then we checked the status of the PRA trunk using this commnad " show pralink " 

we found that the link status is in request state not IDLE state 

Then we checked if the peer side enable the CRC and they confirmed yes , so we enbale it from the U1960 side as per this command 

config modify board slot slot type type trunkport trunkport officeno officeno crcflag yes

After that we tried again and found the calls went normally
