[asterisk-ss7] SS7 link setup between Telsis and Asterisk

[Deepika Nijhawan]

Hi Mesbah,

 

I just connected first E1 of telsis into asterisk trunk 5(which is second
4E1). Link came up on both Telsis and Asterisk. But it is showing yellow
alarm on dahdi trunk. Please see debugs below:

 

1.    Link status is up

asterisk4*CLI> ss7 show linkset 1

SS7 linkset 1 status: Up

 

2. ss7linktest is still showing resource as busy

[root at asterisk4.uk:~]$ /root/download/libss7-1.0.2/ss7linktest 16 itu 13961
13961

Could not open device 16: Device or resource busy

 

3. User part changed to STD_TEST  but it was ISUP before.

asterisk4*CLI> ss7 set debug off linkset 1

Enabled debugging on linkset 1
