what are different reasons for call muting.9th December 2011 at 13:10 #52595abcGuest
we have the same problem too.
During MOC, calling party (let say A party) get silent and doesn’t hear anything even the dialing tone, but the called B party can hear very well A party voice call.
After A party hang up and redial again B party, the conversation is normal and they both can hear each other.
There isnt a specific location where this happen.
what can be the problem?9th December 2011 at 21:44 #52596VanGGuest
what is your network vendor and phone vendors which have these type of problems?
Are there AMF_FR or TFO activated?13th December 2011 at 10:15 #52597abcGuest
Our network vendor is nokia, and this problem has happen in nokiae52, iphone, htc, so I suppose that is not a phone vendor problem.
AMR-FR and TFO ia active in our network.
Do you have any idea what can be the problem?

1.Pls check your A- & Ater interface circuit mapping,there might be some configuration issues in some circuits.
2.In case of MGW,pls check for any Ater configuration Failure Alarms.
