Using the sketch provided in this chapter, write a script to send PSTN calls to a PSTN Gateway. You can use phpMyAdmin, or the MySQL command line to insert data on the database.
Step 1—Add the gateway address in the trusted table using SerMyAdmin:
If desired or convenient, you can instead use the MySQL command line interface to achieve the same result.
#mysql –u openser –p -- enter your mysql password -- mysql> use openser; mysql> INSERT INTO trusted ( src_ip, proto, from_pattern ) VALUES ( '10.1.30.22', 'any', '^sip:.*$');
The records above tell the OpenSER script to allow requests coming from the IP address 10.1.30.22
with any transport protocol, matching the regular expression ^sip:.*$
. You can use the following command if you don't want to reload OpenSER.
#openserctl fifo trusted_reload
Step 2—Include your served domains in the domain table (if you have not done before).
openserctl domain add sermyadmin.org
You can also use SerMyAdmin to do...
