[asterisk-ss7] asterisk-ss7 Digest, Vol 71, Issue 3

[Anita Hall]

Hi

The update is that chan_ss7 worked flawlessly on my link with mostly default
settings.

So that means the link is not making error. Perhaps there is a bug in libss7
or some config problem. I will update.

Thanks for looking at this.

Here is my working chan_ss7 1.4.3, wanpipe 3.5.18 and asterisk 1.6.2 config
files that work with Sangoma A108 card.

# cat /etc/asterisk/ss7.conf
[linkset-siuc]
enabled => yes
enable_st => no
use_connect => yes
hunting_policy => even_mru

[w1g1]

It may be noted that wanpipe1.conf for libss7 and chan_ss7 is the same with
both having TDMV_DCHAN = 0

# cat /etc/dahdi/system.conf
loadzone=us
defaultzone=us

#Sangoma A108 port 1 [slot:4 bus:5 span:1] <wanpipe1>
span=1,1,0,ccs,hdb3
bchan=1-31
echocanceller=mg2,1-15,17-31


Note that in dahdi/system.conf all channels are defined as bearer channels.
chan_ss7 deals with the "D Channel" or signchan in its internal space as
defined in ss7.conf
