FAQs

Q: Is this module for analog phones (FXS) or analog PSTN lines (FXO)?
A: Neither. It specifically terminates DID analog trunk circuits for PBX-style inbound dialing.

Q: Do I need additional DSPs for this card to work?
A: Yes. Voice features, codecs, and echo cancellation use the router’s DSP (PVDM) resources on a supported voice network module.

Q: Which routers support this VIC?
A: Selected voice-capable models in the 1700, 2600/2600XM/2691, 3600, and 3700 Series with VIC/VWIC slots. Check the platform hardware/IOS feature matrix for exact support.

Q: Does it require a special IOS license?
A: It requires an IOS image with voice features; no separate license on the module itself.
