SIP Trunking
The growing demand for converting between VoIP and PSTN networks has given birth to the VoIP termination business model.
Increased Calling Capacity
SIP trunking allows taking part in the lucrative market for VoIP services, and to offer low call rates to businesses for routing calls between ISDN BRI or E1/T1 PRI to the IP networks. SIP trunks enable direct connection to an Internet Telephony Service provider (ITSP) for benefiting from increased calling capacity at generally more attractive prices.
Hypermedia SIP trunks are linked up to the PBX phone system using VoIP interfaces, and can either replace the access to the fixed line provider, or enable an additional voice path.
Ideal for alternative service providers and call origination / call termination vendors, SIP trunking is also relevant to large corporate enterprises who have high volumes of VoIP traffic.
