Avaya to FreePBX - D-channel in service, B-channels OOS/FE-PINS

FreePBX Installation / Upgrade
1

I have an Avaya G3si, release 7 connected to FreePBX 2.5.2.6 via a cross-over cable attached to an integrated CSU on a TN464 DS1 card. The d-channel is in service, however, the b-channels are showing out of service/far end (Asterisk.

I have an exact setup between Avaya (CM4.1) and Free PBX 2.5.2.6 in another location and all is fine. I have set up the same systems exactly but for some reason I cannot get the b-channels in service.

Avaya config is:

It must be in the module loading order

What am I missing? Any help would be greatly appreciated!

Just to let you know that I have this up and running. All the config blogs to set up communication link between Avaya and Asterisk states to use a TN464 DS1 card on the Avaya side. I decided to try my luck and put in a TN767 DS1 card. As soon as I reconfigured for that card, all the B-channels came up in service and idle. I was able to make calls between the 2 systems.
Go figure.
Thanks for replying back to this post. I appreciate your help.

Try changing the switchtype first and see where that gets you.

It’s probably some permissions issue on your zaptel.conf, try the chmod command. You may have to login as root.

Thanks, I am not able to change the span from 1,1,9=9, esf,b8zs, it states “write failed” when I submit.

Try setting switchtype=national and possibly signalling=pri_cpe and maybe even span=1,0,0,ESF,B8ZS in your zaptel.conf. Don’t remember what the numbers mean in the span= settings though. Depends on which one supplies the timing signels I think.

Note:
I’m running asterisk 1.6.2.17 with dahdi not zaptel on this box.

From my chan_dahdi_groups.conf connected to a telco t. As I recall there wasn’t really too much of a difference when I had a Lucent switch at my location.
