Detect caller ID from PSTN

(1/4) > >>

Islander48:
Our telco sends out caller IDs from both landlines and mobile devices. We know this because whenever we receive a call on a mobile device we can see the caller ID (number).
I want to route certain incoming caller IDs through the AA but the Obi110 does not seem to recognize incoming caller IDs. I know this because the call history (accessed through the local portal) does not show any CID for such calls. How can I access the CID from the PSTN line? And is it possible to route it through the AA?

This does not necessarily mean that your Telco is sending CallerID on PSTN landlines to your phone / OBi. Many companies charge for that facility.

How CallerID is sent on a landline will also vary depending on where you live. FSK (Bell 202) is common in North America, FSK (V.23) in UK and there are others.

After a call through an OBi look at Status > PHONE & LINE Status > LastCallerInfo. If CallerID is present, then it should show it there even if the OBi is not set up correctly to process it. If it is there, then try the options under Physical Interfaces > LINE Port > Port Settings > CallerIDDetectMethod. If the method is  FSK (Bell 202), then you may need to make sure that Physical Interfaces > LINE Port > LINE Port > RingDelay is long enough to process CallerID, which arrives after the first ring - at least 4000 (4 seconds).

If CallerID is received and processed by the OBi, then it can be used to route those calls through the AA and other routing tricks.

LastCallerInfo says .. so I suppose caller ID is not available?

That's counter-intuitive!  As to whether it is true or not I don't have any evidence but ianobi 's words are never to be treated lightly.

Try disconnecting the OBi110 and connecting a different device that can receive CallerID. For example, most DECT phones will decode CallerID.

Also, ask your Telco if they send CallerID on PSTN lines and if so, what format is it sent in.
