I am trying to get a trunks working for a DID I have with DIDWW but they seem to use a whole range of IP addresses and the documentation and forum posts I can find are a few years out of date. Does anyone have any current advice or solutions?
Have you allowed these IP address in your firewall? https://www.didww.com/Knowledgebase/the_list_of_didww_ip_addresses/
From what I remember they have two main IPs for SIP signaling - 220.127.116.11 and 18.104.22.168.
Try to add those two in incoming trunks and allow ranges 22.214.171.124/25 126.96.36.199/25 in firewall for audio.
I hope that solves your issue!
Thanks very much, I’ll try just that!
This works for us. We create the main DIDww trunk in the GUI and then setup inbound trunks
for each additional IP in sip_custom.conf like below all pointing to the same context “from-trunk-sip-DIDww”.
This will also open up the ports in the integrated firewall.
host = 188.8.131.52
