Please send ethereal trace if you have it with you to figure out the exact reason.

Subject: ASR Analysis for SIP Trunk Group
Importance: High

We were constantly monitoring ASR in our Trunk Groups and found that ASR [Answer Seizure Ratio] is extremely small in SIP Trunk Group between ZTE ZXC10 GMSC and Huawei MSOFTX3000 MSC.

We took trace on SIP Trunk Group for 20 mins and analyzed the failure codes.

We found striking results:

Failure Codes



Count

Request Terminated 487

244

Temporarily Unavailable 480

37

Server Internal Error 500

38

Busy Here 486

2

Call/Transaction  481

1

Server Timeout 504

12

Not Found 404

1





Total

335










Out of 335 failures, 244 failures are from Failure Code 487

Network Doctors here please help to find out what is the exact problem in the network, so that I can fix it and can increase ASR in our SIP TGs....

Thanks!!!
