Inbound - SIP Origination/SIP Trunking
SIP origination allows a POTS telephone number to be dialed by anyone and answered by a SIP phone. SIP providers have thousands of POTS phone numbers nationwide or within selected area codes that can be assigned to their subscribers. In turn, subscribers let family, friends and customers dial up their SIP phones from local, toll-free numbers.
Outbound - SIP Termination
SIP termination lets subscribers call cellphones and landlines from their SIP phones. The rates vary depending on country and provider. See SIP and POTS.
