Hi,
Wich type of Isdn phone do you use? What is line distance from TN556 port (should be in 900 meters range)?
What type of calls is disconnecting- only off-premises or calls to extensions is disconnecting too?
I think that terminating resistor 100 ohm needs only in high theoretical discussions.
-) Some Professors may be correct me now. In normal life IMHO you don't need this one.
As an idea for outgoing disconnect problem, try to check system-parameters features for
Off-premises Tone Detect Timeout Interval. It should be 20 seconds or a little more.
I had so kind of problem with BRI video calls wich were disconnected after
20-30 seconds of call in-progress(it was too short tone detect timeout).
