I have VOIP phone lines - can I use CapTel?

Yes, some CapTel models support VOIP service. CapTel 840i / 800i / 880i / 2400i models are all compatible with VOIP phone service (high-speed Internet access is also required with these models).

VOIP service is not supported for CapTel models 840 or 800 unless you use 2-Line CapTel. In a 2-Line CapTel setting, the VOIP service can be used for Line 1. Line 2 must be analog.

For CapTel 840 / 800 users who do not use 2-Line CapTel – VOIP service is not supported. The telephone line must be traditional analog or DSL with appropriate filter.
