[asterisk-ss7] chan_ss7.c: Failure in ZT_SPECIFY for circuit 1: Device or resource busy

[ADEGOKE ARUNA]

Dear all,

I realise this list is for the expert, however, you can make me an expert
too when you find time to help me out.

Can somebody give me a working ss7.conf?
I have a 4 E1 to my provider (using Alcatel s12) and I have only one
signaling link.

The opc and dpc are in decimal.
Each time I run the asterisk it gives errors below

Ss7.conf is as below
[linkset-siuc]
enabled => yes
enable_st => no
use_connect => yes
hunting_policy => even_mru
subservice => auto

[link-l1]
linkset => siuc
channels => 1-15,17-31
schannel => 16
firstcic => 1
enabled => yes

[link-l2]
linkset => siuc
channels => 1-31
schannel =>
firstcic => 33
enabled => yes

[link-l3]
linkset => siuc
channels => 1-31
schannel =>
firstcic => 65
enabled => yes

[link-l4]
linkset => siuc
channels => 1-31
schannel =>
firstcic => 97
enabled => yes

[host-WIRELESS2]
enabled => yes
opc => 900
dpc => siuc:60
links => l1:1,l2:2,l3:3,l4:4

I am using sangoma A104D which I confirmed from them and the sangoma said it
works with chan_ss7.

Can someone help out?

You don't need to do that. You can make your ss7.conf look like this:

; First E1 with signalling on timeslot 16
[link-l1]
channels => 1-15,17-31
schannel => 16
firstcic => 1

; Second E1 with no signalling and audio on 31 timeslots.
[link-l2]
channels => 1-31
schannel =>
firstcic => 33

Yeah. It would be a shame to have unused timeslots on an E1. fortunately you
can avoid this :)
