Jola offers SIP trunks as an alternative to standard telephone lines and ISDN (Integrated Services Digital Network) lines, which are being phased out. SIP Trunks run over an internet connection. QoS (Quality of Service) will normally be applied both upstream and downstream to protect time-sensitive voice packets. Our SIP Trunks can be used to connect on-premises equipment and cloud-hosted phone systems to the PSTN network. We offer options for bundled or wholesale call pricing. Our bundles include UK landline and UK mobile calls on 1-month and 12-month contracts.
High Availability SIP (HA SIP) is a SIP trunk with two SIP Gateways, in geographically disparate regions, connected to one or more customer (CPE) endpoints. Our HA SIP Trunks offer high availability and come with failover support. They can also support multiple IP addresses.
International Numbering & Two-Way Calling
JolaCalls has multiple international number products. Inbound Only Numbering is available in 160+ countries. Two-way calling solutions are also available which include local break-out and emergency services calling. Our automated ordering process helps partners meet required regulations.
Region Zoned SIP Channels
Region Zoned SIP Channels offer customers the ability to acquire two-way numbers without incurring per-minute inbound costs. Instead, customers purchase the required number of channels based on their desired maximum concurrent calls on a SIP trunk*. These channels are associated with specific zones, which include multiple countries, eliminating the need to purchase channels for each individual country. Partners can easily order a SIP trunk with the necessary zoned channels through SIP Manager.
* A SIP trunk can only have a single zone.
