Asterisk SIP Trunk to Broadsoft behind an Edgemarc 4550 using Transparent Proxy

Asterisk SIP Trunk to Broadsoft behind an Edgemarc 4550 using Transparent Proxy

NOTE** I use the SBC with IP of 10.x.x.60 for labvoip.cableone.net platform as outbound proxy. I do not set this globally as other calls try to go back out the proxy/SBC and never reach the internal extensions. So I use this in the trunk register => line for inbound calls and the [6026356917] for outbound calls.

Edgemarc 4550 setup:

·         LAN network 192.168.1.0/24

·         Edgemarc LAN IP 192.168.1.1

·         WAN network 10.137.128.0/24

·         Edgemarc WAN IP 10.x.x.18

·         Manually entered my DNS

·         DHCP on and using defaults

·         I have allowed http and ssh in firewall settings

·         I have port forward 2222 from WAN to port 22 for PBX IP (192.168.1.10) in LAN. Just for management outside the LAN.

·         I have port forward 8080 from WAN to port 80 for Phone IP (192.168.1.20) in LAN. Just for management outside the LAN.

·         Transparent Proxy is on under NAT

Asterisk server network setup

·         LAN IP 192.168.1.10/24

·         Gateway and DNS set to 192.168.1.1
