Connect to Asterisk from WAN (Behind Cisco ASA)
Posted on 2011-03-09
I need to allow about a dozen remote employees to access our Asterisk server with their Polycom 450's without the use of VPNs.
I've moved the * server to the DMZ interface on our ASA, and have assigned it a public IP.
In sip.conf I've added externip = xx.xx.xx.xx
On the ASA, I've opened up the following ports to the * server:
69 UDP (for TFTP access).
I cannot get the phones to connect to the server. I've also tried/failed connecting X-Lite as well.
Any help is greatly appreciated.
