If you have an on-site CRM or your CRM has IP restrictions in place, you will need to add rules to your firewall or security settings to allow communication with the following hosts:

api.callinize.com: 54.83.36.230
processor.callinize.com: 54.235.151.43
52.7.87.234
54.198.14.148
104.196.41.186
104.196.2.25
104.196.126.185
54.235.107.161
54.197.230.20
52.4.22.210
52.5.149.54
52.29.201.23
52.28.180.30
52.58.28.102
13.90.214.176
13.92.134.198
13.92.131.115
45.55.102.88
45.55.116.240
45.55.117.64
188.166.194.182
188.166.194.183
188.166.194.184

Examples:

– Your CRM is hosted on-site and you have firewall rules in place that prevent traffic from most servers.
– If you use Salesforce and get a Salesforce 400 error on login/connection, this is likely due to IP restrictions.

If your phone system is behind a firewall or has restrictions, please email us to get the IP address rules for your particular phone system.
