Transmission issue?

Check the alarms in your BSC and see if there is any active since the time you had this problem.
And almost all the time this problem was related to transmission as patek asked.

Ussually transcoder issue might become root cause

1st action to conduct comprehensive call trace
2nd action to get PCHR and analyze using NPMaster by modul noise voice

Hi,

Generally this problem happening due to unsync frames in air interface but i have seen such issue due to RNC or CS core software bug as well. So at first be sure was there any SW upgrade before appearing such phenomena or not. Consult with Huawei support team most probably they have correction patch in conjunction.

Cheers
