[Serusers] Remote Party ID - sr-users

12 Jul 2004


      We have downloaded the latest ser software from cvs in order to support appending of remote party id while using mysql as the ser database.
After compiling and installing the ser software we included the auth and auth_db parameters and also the append_rpid_hf() function in our ser.cfg file as shown below.
SER server starts and registration is successfull however when forwarding to the pstn gateway, ser will not append the remote party id header, even if the rpid and uri columns in mysql database are populated accordingly using the serctl add rpid command. Calls are also successfull however the gateway will not include the calling party number in the setup message because the rpid header is missing.
Any ideas please?
Thanks
Charles and Andrew
