SIP trunking is a service that provides voice connectivity between a business's PBX or communication platform and the public telephone network (PSTN) over an internet connection, replacing traditional phone lines.
SIP trunking reduces telephony costs by eliminating physical phone lines and enabling pay-per-use pricing. It supports dynamic channel allocation, disaster recovery routing, and geographic number portability. Businesses can scale channels up or down instantly.
InboxCentral supports SIP trunking through integration with Tata Tele, enabling businesses to connect their existing phone infrastructure with the omnichannel platform.
