If your telco does not provide far end disconnect supervision or if they just dont do it well you may need to “fake” supervision in order for your lines to disconnect properly. You may fake supervision by adding a few lines to your zapata.conf .

Add the following to your /etc/asterisk/zapata.conf

callprogress=yes
busydetect=yes


After doing this restart asterisk. There may still be a disconnect delay but it will be reduced.

Below is the instructions from our PCI manual on configuring your rhino T1 as an E1. You will use the appropriate insmod command as apposed to modprobe.

If you have a R4FXO-EX or R4FXO-EC and have upgraded to the RPM version of our drivers or if you use our new driver method and your card stops working you may need to upgrade your hardware.

There are a few ways to install our pci drivers, no matter which method you choose you only need to do it once for all Rhino cards including legacy cards. This means if you have followed these steps once and are simply adding a new card, no further software installation is needed.
