# t38modem must be rebuilt on every {ptlib,opal} version or options change or you'll get segfault

# TODO: Update Readme.txt with github links, new versions and improved command lines
# TODO: Can we get multiple STUN servers for redundancy?
#+TODO: The routing patch 0001 sucks. What is the correct patch?. Routing fixed.
#+TODO: Need fax call log without all the riffraff, patched away noisy lines
#+TODO: Quiet option to reduce OPAL chatter, patched away
# TODO: Do we get disconnect and reconnect on Internet failover?
#+TODO: Do not show password on command line, patched to show length
#+TODO: Do not show password on screen in systemd log, patched to read from file
# TODO: How to set up redundant connections
#+TODO: Delete /dev/ttyT* on exit, handled by watchdog
# TODO: --rtp-max must always be odd number

# Until patch 0001 is fixed, we need a separate package for each service
# Patch 0001 is now fixed. No more need for separate package.

# Edit /etc/t38modem.sh with service parameters
# Passwords should not have any special characters that interfere with sed !#_-= are ok
# Password is gone, no longer removed by sed.

# For first service
# systemctl enable --now t38modem

# For additional service
# systemctl enable --now t38modem@ttyAC

# Use the watchdog if you find t38modem hangs. Some crashes are restarted by systemd and some hang.
# systemctl enable --now t38modem-watchdog.timer
# systemctl enable --now t38modem-watchdog@ttyAC0.timer

# In your router create UDP port mappings for UDP+RTP ports. Source lock them to your provider static IP.
# Set the ttl to 100 more seconds than $g_sip_expires (t38modem.sh)
# Verify that the TTL is correct
