A gateway that initiates an ISDN call based on a SIP call or vice versa is reasonably straightforward, as sketched in figure.

You would need a Media Gateway which can take inband siganling such as PRI send it to call control of softswitch. Softswitch which look into translations and send the the call to SIP. Basically you would need Media Gateway to convert PRI to SIP or ISUP and vice versa. Please look at website like Taqua, Metaswitch and Genband those are leaders in this interconnect Media Gateways
