Hello,
I am newbie in Asterisk. If I have to add 100 users at sip.conf, then How Can I add those 100 users at a time.
I am configuring sip.conf as below
As you are new to Asterisk and seemingly just starting out I would suggest not using chan_sip as your channel driver. This is a legacy channel driver, and will be officially deprecated in Asterisk 17.
Instead please use the chan_pjsip channel driver and resources instead. More information on configuring your pjsip.conf can be found on the configuring res_pjsip wiki page (along with loads of other information about the driver).
And depending on the version you are using you can ease your configuration burden by using the pjsip configuration wizard.
