Ztdummy issue

Yo Guyz! I got some problem here with the ztdummy. It creates a lot of echo and delays in the Meetme conference. I searched for some help and i came upon this bugs.digium.com/view.php?id=4301.

They said i need to patch it, but i have no idea to patch which one and issit for stable version or the beta version or the cvs head version. :open_mouth:
btw i’m using asterisk and zaptel version 1.2.0 beta. Any ideas guyz?? Thankz!
