ss7_default_echocontrol=yes
You cannot do:
ss7_default_echocontrol=no
because it cannot clear the flag. It just does nothing.
This is true for the following config options:
ss7_explicitacm
ss7_autoacm
ss7_initialhwblo
ss7_use_echocontrol
ss7_default_echocontrol
there are more as well.</pre>

Also when we send RSC we expect to put the cic in service if it is not remotely blocked and upon receipt the remote host should clear its remoteblocking state, so it should be correct to have it always cleared.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">ss7_do_rsc() is called by sig_ss7_hangup() and ss7_start_rsc() directly.
ss7_start_rsc() is called by sig_ss7_reset_cic().
isup_handle_unexpected() in libss7 can set the do_hangup to SS7_HANGUP_SEND_RSC which in sig_ss7_hangup() will then call ss7_do_rsc().</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I think it should be trusted because it is controllable by dialplan and the connected line interception routine.
Also id.number.presentation == 0 is a valid combination of the presentation and screening field values. (SS7_PRESENTATION_ALLOWED, SS7_SCREENING_USER_PROVIDED_NOT_VERIFIED)</pre>
