I am using “Asterisk” to make calls to the PSTN network. For this purpose, I have installed the TE420b card and softwares including dahdi, libpri, asterisk …
DAHDI: 3.2.0
libpri: git version
asterisk: 20.4.0
I want to perform a test by simply making a call to the PSTN network using asterisk to the phone number 1111111111. To do this, I obtained the phone number 2222222222 from the PSTN service provider and connected it to the E1 line (span 4). (making call to 1111111111)
What changes or additions do I need to make in the current state to be able to make the call? Even if it succeeds only once, that would be fine.
Here are the results of some commands:
> pri show spans
PRI span 1/0: In Alarm, Down, Active
PRI span 2/0: In Alarm, Down, Active
PRI span 3/0: In Alarm, Down, Active
PRI span 4/0: Up, Active
> dahdi show status

Also my asterisk continuously making the following

Thank you.
