I've had many odd issues with Zaptel since jumping from 2.2.4-32 to the newer point releases and finally regressed back to 2.2.4-32... the most notable is that the 2.2.4-54 release in particular calls DAHDI as the technology for internal Zaptel FXS hardware so fails... example AGI Debug for Sail-2.2.4-54, Asterisk-1.4.21.1, and zaptel-1.4.12.1 compiled from source on the 2.6.9-89.31.1 kernel for X1200 Polycom calling x1100 Zaptel FXS station:

NOTE: other functions like Call Groups and Inbound routing work fine calling Zaptel FXS hardware.
Additionally since moving to the newer releases the Zaptel hardware would periodically cease to function on a Reconfigure or Reboot and I've had to reinstall Zaptel and do a PCI Telephony Cards =>Initialize =>Commit then Power down and reboot to get it functioning again... after having to do this half a dozen times it was simpler to just regress than to troubleshoot.
Any one else using Zaptel with the newer point releases have similar issues?
