Not every business is ready to move entirely to the cloud — and that's perfectly fine. SIP Trunking is the smart bridge between your existing on-premises phone system and the modern IP communications your business needs. Teltek's SIP Trunking service lets you reduce costs, add new capabilities, and extend the life of your current phone system — all without starting from scratch.
Teltek has been delivering business phone systems and telecommunications solutions to businesses in Maryland, DC, and Florida since 1996. We understand legacy premise-based phone systems and know how to modernize them — practically, affordably, and without disruption.
SIP (Session Initiation Protocol) Trunking replaces traditional physical phone lines, like POTS lines, T1s, and PRI circuits, with IP-based voice connections delivered over your existing internet connection. Your existing PBX phone system stays in place; you simply swap out the expensive, outdated lines feeding it for modern, flexible IP connections.
This makes SIP Trunking one of the most cost-effective ways to modernize your business voice services without a full system replacement.
Replace expensive analog lines with affordable IP-based connections. Buy only the call paths you need and get unlimited local and long-distance calling with predictable monthly pricing
If your internet goes down or all lines are busy, SIP Trunking enables instant call rerouting to another location, a mobile number, or any designated backup, so your business stays reachable no matter what.
Thispairs well with Teltek's backup and disaster recovery approach to business continuity.
With traditional PRI lines, adding call capacity requires physical installation — which takes time and money. SIP Trunking capacity can be increased to meet demand within hours, not weeks. Scale up during busy seasons, scale back down when things slow.
SIP Trunking is a natural first step toward a full cloud phone system. When you're ready to migrate completely, the transition is seamless. You can even run a hybrid SIP + Hosted PBX model, using SIP Trunking for existing locations while migrating new sites to cloud.
Teltek has been modernizing business phone infrastructure in Maryland, DC, and Florida since 1996. We understand legacy systems — Avaya, NEC, Toshiba, Mitel, and more — and know how to connect them to modern SIP trunking without disrupting your operations. One partner, one call, no finger-pointing.
