The user guide states that call waiting "settings are controlled in the Feature Codes module, Extensions module, and Advanced Settings module". I have an extension set up with an analog phone attached to a Grandstream HT503. The HT503 in this case acts as a conduit between the analog phone and the PBX (RASPBX to be more specific). The HT503, being both an FXO as well as FXS device also acts as a conduit between a POTS line and the PBX as well. All of this functions very well with the exception of Call Waiting.
Call waiting is enabled for the Extension (and the Extension page shows this) and CW is enabled in the Advanced Settings page. The Feature Codes page, however, does not show the Callwaiting section as indicated in the user guide.
I do not have POTS call waiting and realize that if I am on a POTS call that another call to that POTS line will result in a busy signal for the caller. What I am looking for is to be notified of an incoming POTS call if I am on a digital call or be notified of an incoming digitial call if I am on a POTS call. The current setup sends the call to voicemail which is acceptable but not preferable.
I am unsure as to whether the lack of these settings on the Feature Codes page is due to the use of an ATA or some other setting that I must modify. Hopefully someone here can point me in the right direction.
