Frequently Asked Questions
What is a session border controller and why do I need one?
A session border controller (SBC) like the EdgeMarc 2900A acts as an intelligent gateway between your internal VoIP network and external SIP trunking providers or cloud UC platforms. It provides security, call control, protocol translation, and network address translation—essential for protecting your communications infrastructure while enabling reliable SIP trunking and cloud UC deployments.
Can the EdgeMarc 2900A support both VoIP and analog endpoints?
Yes. The EdgeMarc 2900A includes FXS and FXO ports that allow you to connect analog phones, fax machines, overhead paging systems, and door phones alongside your VoIP infrastructure. This hybrid capability makes it ideal for organizations with mixed endpoint environments or those gradually migrating from legacy analog systems.
How does the EdgeMarc 2900A provide PSTN failover?
The EdgeMarc 2900A's FXO connectivity enables direct PSTN failover, ensuring business continuity if your primary SIP trunking or cloud UC connection fails. Calls automatically route to the public switched telephone network, maintaining service availability during outages.
Is the EdgeMarc 2900A suitable for service providers?
Absolutely. The EdgeMarc 2900A is designed for both enterprise and service provider deployments. Its support for hundreds of concurrent calls, multiple network interfaces, and advanced call control features make it an excellent choice for managed service providers offering SIP trunking and cloud UC services to multiple customers.
