Ubuntu 12.04.5 LTS
Asterisk ver 11.25
chan_ss7 version 2.3.11
4 x Digium TE820 (5th Gen)
We are getting warnings below in asterisk messages:
WARNING[C-0000c183] transport.c: Unable to set fd 988 to audiomode
WARNING[C-0000c183] transport.c: Unable to clear audiomode on fd 988
At the beginning this issue raised only on 2 CICs, after there started to be more.
We tried to block locally and remotely affected CICs but were getting same warning
Can anyone advise what could be the problem?
