DNS Names
The DNS names associated with the services are:
- ccs3.cloudprovisioning.com (for most services). This name will be deprecated in 2020.
- stretto.cloudprovisioning.com (for most services)
- imp.softphone.com (specific to XMPP)
- secure.counterpath.com (for licensing and documentation)
- secure-east.counterpath.com (for licensing and documentation)
All interactions with all services other than XMPP are HTTPS over TLS.
XMPP does also have clients accessing the XMPP server by using DNS SRV if a proxy is not specified, so clients could reach out to customers XMPP domain on ports specified.
IP addresses and DNS names for hosted push servers
The push service uses the following IP addresses and domain names.
Clients should automatically route to the correct nearest regional server, but we recommend ensuring that ALL addresses are accessible in case of traveling users, etc. Please also note that IP addresses may change in the future; if you manually configure your firewall/etc. for these addresses and experience issues in the future, please revisit this page to find the latest information.
Current limitations:
Only IPv4 SIP servers are currently supported for calls involving the push server. The Bria mobile client will support IPv6-only networks utilizing DNS64/NAT64 when communicating with IPv4 SIP servers.
