Hello Folks,<br>
<br>
I have a 2E1 ports board produced by company in Brazil named Aligera<br>
<br>
I have one E1 port connected to PSTN(Embratel) and the other connected to a<br>
digital converter named "Intelbras IC-E1".<br>
<br>
<a href="http://www.intelbras.com.br/ecenter/downloads/manuais/interface_ic_e1.zip" target="_blank">http://www.intelbras.com.br/ecenter/downloads/manuais/interface_ic_e1.zip</a><br>
<br>
It converts 15 or 30 analog lines in one R2 trunk. It converts the<br>
analog trunks from the PBX to R2, connected to Asterisk.<br>
<br>
So:<br>
PBX <--> IC-E1 <--> Asterisk <--> PSTN(Embratel)<br>
<br>
I can send and receive calls through the PSTN line and I *can*<br>
receive calls from the<br>
PBX/IC-E1 side. The problem is when I receive a call from the PSTN<br>
line to the PBX,<br>
the outbound call to the PBX is answered by the operator, I can hear<br>
some seconds of<br>
audio and then it drops.<br>
<br>
My environment is:<br>
<br>
Kernel version: Kernel 2.6.18-164.el5PAE<br>
Distro: CentOS release 5.4 (Final)<br>
Versao do Asterisk: 1.6.2.1<br>

The only weird messages I can find in the logs are:<br>
<br>

<br>
What it should be ?<br>
