We are using a TA916e as a voice gateway - SIP (IP PBX) to ISDN PRI (Carrier).
Occasionally, an IP PBX user would like to restrict the presentation of their Calling-Party Number. When the IP PBX marks the call as "restricted" it signals SIP to the TA916e that includes a Privacy header and a P-Asserted-Identity header. We need the ISDN PRI to set the Presentation flag to "RESTRICTED" on such calls.
We can force the calling-party number presentation flag to be always "ALLOWED" or always "RESTRICTED" under the PRI interface as such:
interface pri 1
calling-party presentation [allowed|restricted]
However, we need the setting of the ISDN calling-party number presentation flag to be dynamic based on the SIP signaling received from the IP PBX.
Suggestions? Thanks!
