Yes, some CapTel models support VOIP telephone service. CapTel 840i/880i/2400i models are all compatible with VOIP phone service (high-speed Internet access is also required with these models). NOTE: While CapTel 840i/880i models support VOIP telephone service, they still require a physical phone cord plugged in to an RJ11 jack. CapTel 840i/880i cannot access VOIP services wirelessly or via the Ethernet connection alone.
If you do not have phone service, CapTel 2400i can be used in Internet-only (VOIP) mode. No phone line required. For more details.
VOIP phone 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.
