I’m using Elastix 2 FreePBX 184.108.40.206 with the VoicePulse module
I’m using VoicePulse for my SIP trunk
I’ve set up a DISA with the default values such as context from-internal
I’ve added the DISA to an IVR and it works as expected. From my cell phone I’m able to dial the main number and choose the IVR number for the DISA and dial extensions or dial out as if calling from inside the office.
The purpose of this DISA is to allow two people to dial from their cell phones into our Asterisk system and make international calls from there since they’re cheaper.
I have a PIN/password on the DISA and a password on the outbound route with the dial pattern for international calls. I want to make this more secure than just those passwords if that’s possible. I’m new to using Asterisk and I’m not sure what my options are. One thing I’d like to try is making it so that only 2 cell phone numbers are allowed to use this DISA. How would I do that? Are there easy ways to make this more secure?
