If you have an existing premise–based phone system, Smoothstone offers two powerful IP Trunking solutions: SIP and TDM IP Trunking. Both allow you to leverage the investment you have already made in your on–site phone system, while enabling you to immediately realize the benefits of IP technology. This also prepares you for a future migration to a fully–hosted VoIP solution when you´re ready.
SIP Trunking
If you already have an existing premise–based IP PBX, SIP Trunking allows you to maximize your system´s functionality by accessing the rich feature set of Smoothstone´s VoIP services without costly new infrastructure, media gateways or upgrades of desktop equipment. With SIP trunking, we deliver reliable, secure and cost–effective connections that provide greater redundancy and higher aggregation of voice call traffic (compared to T1/PRI).

TDM IP Trunking
TDM IP Trunking is an ideal solution, if you are looking for a cost–effective way to access Smoothstone´s VoIP service and features without wholesale replacement of your existing PBX, key system. It replaces existing frame relay or data–only WAN infrastructures, allowing you to converge voice, data and Internet over a single, dynamic circuit.

Unmatched Flexibility
Both IP Trunking solutions provide the added flexibility of allowing you to connect to the Smoothstone network over any underlying carrier´s MPLS network. Smoothstone is among the few providers experienced enough with SIP and MPLS to accept connections over third–party MPLS networks. This allows you the convenience of preserving existing network connections and reduces deployment time for your overall VoIP solution.
No matter which IP Trunking solution you choose, both offer valuable benefits including:
