[Freeswitch-dev] Disconnect cause FTDM_CAUSE_SUBSCRIBER_ABSENT problem

[David Yat Sin]

Hi Juraj,
It looks like cause = 20 is not in the list of allowed values inside
libsng_isdn. Cause 20 is valid, so this is a bug.

Can you create a ticket on JIRA, project=FreeTDM for this, and assign it
to me (David Yat Sin).

David
