I have been trying to understand how the isup-oli parameter is being implemented. From what I can tell it seems to be mainly implemented as a SIP URI parameter and used in the From header. I have not seen it used as a parameter to a tel URI, nor in headers other than "From:"
Also, in lieu of an RFC specifying this parameter, are folks implementing this from any specific document? Cheers _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
