Silent calls

[justdream]

Experts,

I face a problem of getting silent calls from both parties (I mean both the caller and the calling person couldn't hear each other)

Do you know what's the root cause of this problem and how to solve it?

Please check on up-link voice and check on the transmission also like (MW Optic...............)

Do you mean GSM? What vendor made the equipment?
It could have many causes, Transcoder or the MSC or the BSC voice coding boards.
I think first a BSC engineer should look at the traces on the BSC and to check if there is anything in the fault files. It should be also checked on the MSC if there are errors reported.

in my personal experience.. first I will check the office that are involucrated to the destination call, I agree with TEMS checking Tx, in some cases the trouble begins with crossed cables in DSX or something that avoid the speech, if there is no a Tx problem maybe you could check Transcoders or something at upper level than BTS
