In addition to our powerful API we offer a number of features that work alongside it which are implemented in the SIP protocol itself, as custom headers sent in the initial INVITE from your equipment, or in our responses. These include per-call control of things such as;
- Billing Reconciliation / Call Tagging
- Trunk Assignment
- Anti Fraud / Revenue Protection (max cost per minute)
Along with helpful, human readable, responses when a call fails due to a limit you’ve set using our API or new portal.
Due to the ever increasing number of features we’re adding at the SIP level, we’ve compiled comprehensive documentation of all the Simwood SIP Extensions to complement our API Documentation.
