Hi guys Successfully installed and compiled patch into asterisk source. For info purposes, we are using an old trunk version, revision 66959 to be exact. with the patched version our initial tests resulted in soft to no noticeable echo. A little adjustment on zapata.conf might eliminate the soft echo. We'll do some more softclient tests and update this thread later. Thanks to evryone for your help and to Mathew for the patch file. It worked like a charm Keep up the good work guys. Thanks Chris -------------- next part -------------- An HTML attachment was scrubbed...
