Issue Description
The phone hanged under IAD132E (T) calls fixed phone in Changchun, it prompts that “sorry, the number you dial doesn’t exist, please check and dial again”
Alarm Information
Sorry, the number you dial doesn’t exist, please check and dial again
Handling Process
IDA will get digital image when IDA refresh soft switch register, and knows the soft parameter switch of soft switch is opened, then, when user dial the numbers, IDA will match the digital image, analyze the message feedback by scene engineers, the digital image soft switch sent to IAD is 04[135][02-9]xxxxxxx, and it’s 11 bit, so the number of 043266028971’s first 11 bit just match the digital above. So IAD report and the last bit is deleted.
If we report 12 bit number, we suggest opposite change digital image to 12 bits, after soft switch change the digital image, problem is solved.
Root Cause
IAD132E(T) and Ping through soft switch;
Check IAD132E(T) register state, the state is Normal;
The number is opened by the operator, suggest the engineer at scene to repeat the malfunction. Use the phone under IAD132E(T) to call 043266028971 of Changchun, and catch the network message to analyze
Suggestions
If IAD access the soft switch through mgcp protocol, the digital is sent by soft switch, the digital image need to be changed by the soft switch side.
If IAD access the soft switch through SIP protocol, IAD itself can set the digital image; the corresponding changes should be decided by the scene.
