Subject: [asterisk-users] Voice only works from one way.<BR>
<BR>
Hello, everyone.<BR>
<BR>
Right now, we are trying launch our own PBX system based on Asterisk(Fedora)<BR>
with Cisco 2611. Cisco has 2 port FXO card installed on it.<BR>
<BR>
For testing, I have 2611 hooked into phone line with number of xxx-xxx-xxxx<BR>
fine. (I'll call it F). Using softphone, I can dial in extension 1001 on<BR>
asterisk, which should talk to cisco. After initial connection to Asterisk,<BR>
I have try to call F, and it will ring. Voice from softphone to F carries<BR>
over and I can hear it; however, no voice from F to softphone will carry. I<BR>
have been experimenting with different codec and other cisco/asterisk config<BR>
tips from the web. None had worked so far.<BR>
<BR>
If anyone have experienced such problem and knows how to solve this, I will<BR>
be eternally grateful.<BR>
