Hi,
I am using 1.6.0.26, with chan_ss7 and chunk size 80 as I found the
1.6.1 and 1.6.2 branches unstable. I have a A108 with HWEC.
The patch chan_ss7-1.3-160.patch will allow you to patch chan_ss7-1.3 so
that it will compile with asterisk-1.6.0.26
First install the vanilla dahdi-linux-complete-2.2.1+2.2.1
Then install wanpipe 3.5.10 or 3.4.8 and specify chunk size 80. I am
using 3.4.8.
(Install asterisk if it is not already installed).
patch chan_ss7 with chan_ss7-1.3-160.patch so that it will work 1.6.0.26
Then patch with chan_ss7-1.3-160-chunk80.patch so that chunk size 80
works with chan_ss7.
Cheers,
Amish

hi all,
Can you please help me out? I tried setting up asterisk-1.6.2.6 +
wanpipe-3.5.10 dahdi-2.2.1.1 and chan_ss7-1.3.
i got the signalling up but its lost the signalling to t7 timeout
after a while and i have to restart wanrouter and asterisk to get the
signaling INSERVICE again.
i have done my little effort without luck, I have tried disabling the
sltm but i keep getting unknown config option in ss7.
kindly help.

We have managed to make it work with DAHDI_CHUNKSIZE 40.
We use:
- Sangoma A 108
- Chan_ss7 1.3
- Dahdi-linux-2.2.1
It works but we don't know for sure how stable it is. I would be very
thankful if someone tries and give us some feedback.
