SIP Signaling Addresses

VOIP Awesome SIP Proxies are located in different regions. Besides the sip.voipawesome.com domain, you can choose which region to use by configuring your SIP device to use any of the region specific SIP proxies:

United States, East
FQDNIP Address
sip-us-east.voipawesome.com45.77.198.219

SIP Regions affect only the SIP signaling path. Please note that the RTP media has a different set of IP addresses, please refer to the Media/RTP section of this document.

Note that outbound calls are limited to 50 CPS (call-setups per second) per IP address; this is subject to change, up or down.


DNS Records

The FQDNs for each region support DNS records types A, SRV and NAPTR.

The DNS A records resolve to the primary IP address, while the DNS SRV and NAPTR records will allow you to use both IPs, primary and secondary, while also discovering the available transport protocols and their ports.
