The Sea Softswitch provides advanced support of SIP trunks. SIP trunks allow enterprises to be connected directly to their ITSP (Internet Telephony Service Provider) through a pure IP connection. This feature allows customers to comply with service Level Agreements and ensure QoS, as well as significantly reduce costs.
The Sea Softswitch also uses SIP trunks to interconnect to 3rd party softswitches that are standard compliant and support SIP. The interconnectivity between the Sea Softswitch and 3rd party softswitches can be done through TDM based QSIG via the Wave Gateway.
