Description (partial)


Caller-id is not displayed for the second call to a FXS port.


SIP Server -[sip]- Gateway (fxs) -- Analog phone

This is seen to occur when the Device Service Application (DSAPP) is enabled on the gateway to provide supplementary features for the phone connected to the FXS port using SIP. Configuring either 'caller-id enable' or 'caller-id enable type 2' on the FXS voice port will trigger this issue.
