VoIP Services

 

There are six VoIP services provided by a Excel platform equipped with IP Network Interface Series 2 cards.

1. VoIP_Report

2. VoIP_Configure

3. VoIP_Query

4. VoIP_Allocate

5. VoIP_Update

6. VoIP_Deallocate

From the IP Network Interface Series 2 card perspective, the external host is transparent. The host can be a SwitchKit, Softswitch, third party, or other. The six VoIP services provide configuration and call control using API messages. The following is a list of messages used by the host to use the above VoIP services.

Important! The API messages in BOLD have been impacted by the integration of IP Network Interface Series 2 card.
