I have VOIP phone lines – can I use CapTel?
Yes, some CapTel models support VOIP service. CapTel 840i/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 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 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.
