 SIP Trunks provide a secure, resilient and feature rich PSTN/ISDN
replacement solution via a direct VoIP based solution. 

HOW SIP WORKS

Your Call Telecom SIP service delivers the SIP trunk connections across customer sites.
It seamlessly connects to a customer’s platform via a customer’s network for all inbound and outbound calls. It provides superior scalability in comparison to traditional voice infrastructure and seamlessly integrates with your existing VoIP equipment.

SIP provides the opportunity to significantly reduce the current ISDN/PSTN tariffs from on-premise PBX’s by implementing converged voice and data traffic over a single ‘pipe’ into the carrier network. Typically, the Point A end of the SIP trunk is connected to the organisation’s PBX. The PBX system must have a SIP trunk interface, which is typically a “native IP interface” looking “outwards” from the customer’s telephony system. Traditional telephony systems can also make use of SIP Trunking through interconnection with a front-end SIP gateway or ISDN Access Device (IAD).

Therefore, as voice traffic leaves the PBX’s SIP trunk interface, it is routed via the carrier’s or service provider’s IP access and core network. The call is then routed to our media a gateway to the PSTN network.
The Point B, or other end of the SIP trunk, connects from the carrier’s IP network via the appropriate PSTN gateway into the carrier’s PSTN network.

WHY YOUR CALL TELECOM SIP TRUNKS?

Benefits

Easy to manage
Simplify moves, adds and changes to your service. Have one provider with one bill and one point of contact. Receive 24/7 local support to minimise hassles and improve business productivity.
Streamline infrastructure
Can reduce the expense and inefficiency of separate networks. SIP Trunks are a simple and cost-effective way to make calls within your business.
Independence of Access Network
SIP Trunking is carried over IP networks, meaning SIP Trunking is independent of the access network type. SIP Trunking can be carried over copper, fibre and wireless access networks and as a result is the preferred form of carrying voice traffic over fibre networks.
Gain greater flexibility
SIP Trunking enables more cost effective least-cost routing (LCR) and provides a far more effective and flexible disaster recovery option. It also allows greater flexibility with growth by using our Cloud Infrastructure and Network solutions.
Disaster Recovery
Enhance resilience. In the occasion of any event or emergency, calls can be forwarded on to other destinations almost instantly with no associated forwarding costs.
Secure
A properly configured SIP channel will allow you to handle you own connectivity via dedicated firewalls built in, which is in turn managed by SIP channel maintainers or by Your Call Telecom.
Call quality
SIP Trunking uses private IP connections specifically designed to carry voice, and as such come with Quality-of-Service guarantees. SIP Trunks therefore can deliver better call quality than ISDN

Acting now will ensure you are taking advantage of the benefits of SIP Trunking plus avoiding future disconnections that may disrupt your business.
