How it works
IP telephony converts voice into digital packets. SIP commonly establishes and ends calls; RTP carries real-time audio. These are separate functions: successful registration does not prove that audio works in both directions. A desk IP phone or a software client can be used; supported devices and settings are agreed during setup.

Where it helps
An IP PBX handles telephone connections over an IP network. KEYCom offers its own IP PBX for rent without configuration access. We do not configure customer-owned IP PBX systems or other customer telephone equipment. Available features and rental terms are confirmed before ordering.
What to consider
Call quality depends on latency, jitter and packet loss as well as Internet speed. Confirm simultaneous call requirements and connection requirements before ordering. We do not port numbers from other operators or configure customer-owned IP PBX systems. Our rental IP PBX is provided without configuration access.

Tell us your city and the required numbers and simultaneous calls. We confirm service availability and rental terms for our IP PBX. Pricing, available features and connection requirements are agreed before ordering. Existing numbers are not ported and customer PBX systems are not configured. Service terms are documented in the offer and agreement.
