Hello,

I`ve searched for some Information about FreeSWITCH but couldn`t find anything about it. I wanna use FreeSWITCH with a ISDN-BRI card.

I need to get the User-User Information Element  specified by the ITU-T in Q.931 and transmit it via SIP to the User Agents. Is this possible with FreeSWITCH?

Does FreeSWITCH support the ISDN-Hold supplementary service to free the B-Channels while the call is put on hold?

Is Connected Line identification Presentation (COLP) supported?

best regards,

Michael
