• Hi Ira,

  It should look like this:

  localnet=192.168.1.0/255.255.255.0
  localnet=192.168.3.0/255.255.255.0

  Just making sure you have both local subnets listed on both sides, not just the one.

  No worries, good luck.

  cheers, Jan

• Hi Ira,

  🙂

  The next thing to look at is firewall rules.

• You only need to add the Signaling IPs as peers. The Media IPs only need to be whitelisted in your firewall.

  Furthermore, you can actually trim the list down to only one region by following their instructions here https://www.twilio.com/docs/sip-trunking#OriginationURI-region

• Ira,

  What version of Asterisk are you using, and what channel driver?

  There has to be a better way than to create hundreds of peer entries.
