Voice issues in ChanSpy

Hi,

We have Asterisk version 1.6.2.22 running. We are facing issue in ChanSpy barge in, the issue is that the voice of supervisor (one who initiates ChanSpy(SIP/XXX, qB) ) is breaking, like for the caller (the caller is the one who dials to our IVR.)

If we don’t do ChanSpy, then there are no voice issues for both agent and caller.

What can we do to improve the voice performance?

I am also facing the same issue. Does any one solution for this
