We will be making infrastructure changes to our VoIPon outbound proxy service to improve resiliency.
These changes will be made live on the 21/01/2011 at 23:00.
SIP and RTP traffic will be delivered from different IPs therefore please ensure that following IP address ranges are allowed in your firewall.
We will be keeping the same IPs for your outbound proxy domain so you do not required any DNS changes
For your records these are:
184.108.40.206 to 24
220.127.116.11 to 24
18.104.22.168 to 24
ADSL ranges are:
22.214.171.124 to 24
