I'm using the SPA232D as an FXO port with asterisk. I can place and receive calls between asterisk and the FXO port of the SPA232D, but when receiving calls I don't receive callerID.
I'm in USA. Specifically, I have Comcast as voice provider. I'm not sure what settings to adjust or how to troubleshoot. If I plug an analog phone straight into the comcast equipment (bypassing the SPA232D), it receives callerID. With the SPA232D in place, when asterisk receives the inbound call the CallerID is empty.
I have the following settings in the SPA232D:
Voice -> Regional page, Miscellaneous section:
- CallerID Method: Bellcore (N Amer, China)
- CallerID FSK Standard: bell 202. I also tried v.23, but this did not change behavior.
PSTN page, PSTN-To-VoIP Gateway Setup section:
- PSTN CID For VoIP CID: yes
