D-4 channel bank with FXO cards
My system is asterisk 11 PBX Firmware:10.13.66-8 PBX Service Pack:188.8.131.52 Downloaded the distro and did a Fresh build yesterday as a test system.
Attempting to configure a Digium TE435BF connected to a Telco Systems D-4 Channel Bank equipped with FXS cards.
In order for the system to recognize the TE435BF I had to install the latest DUNDI software from Digium.
After reading what I could find on the internet, I used the DAHDI module and configured the card for FXO KS, D-4, AMI.
Utilizing the Bulk Extensions module 3 extensions where made in the same way that I have done for a FXS Digium card, assigning them to time slots1 & 2 & 3
A T1 DATS test set show Idol conditions on the A & B signaling bits from both the channel bank and the FreePbx system.
Going off hook on the FXS channel on the D-4 bank I do not get any dial tone nor do I see anything on the Asterisk CLI.
When calling the extension I get a 120 IPM busy.
After consulting with Digium Technical support we feel that either I have something misconfigured as the chan_dahdi_groups.conf does not have the expected information in it.
The chan_dahdi_groups.conf as set by FreePbx is
Digium support believes that it should be
This agrees whit what I have read in the Digium manual.
We changed chan_dahdi_groups.conf but it had no effect.
Thus I am unsure that I have configured the DAHDI module correctly and I am unsure that I created the extension correctly.
Any help or ideas greatly appreciated.
