Restcomm REFER is using IP instead of Organization in URI

[croufay]

we have replicated the scenario in our laboratory with the same version as yours (8.3.0-20). I am attaching some information to our R&D team to give us a recommendation with the REFER method.

The modification in RestcommOne Connect 8.3.0-20 is:

Before:

        destinationOrganizationSid = getOrganizationSidBySipURIHost(storage, (SipURI)request.getRequestURI());
        // try to get destinationOrganizationSid from toUril
        destinationOrganizationSid = destinationOrganizationSid != null ? destinationOrganizationSid : getOrganizationSidBySipURIHost(storage, (SipURI)request.getTo().getURI());

After:

        if (request.getMethod().equals("REFER")) {
            destinationOrganizationSid = getOrganizationSidBySipURIHost(storage, (SipURI)request.getAddressHeader("Refer-To").getURI());
            if(destinationOrganizationSid == null){
                logger.error("destinationOrganizationSid is NULL: Refer-To Uri is: "+(SipURI)request.getAddressHeader("Refer-To").getURI());
            }else{
                logger.debug("getMostOptimalIncomingPhoneNumber: sourceOrganizationSid: "+sourceOrganizationSid+" : destinationOrganizationSid: "+destinationOrganizationSid +" Refer-To Uri is: "+(SipURI)request.getAddressHeader("Refer-To").getURI());
            }
        } else {
            destinationOrganizationSid = getOrganizationSidBySipURIHost(storage, (SipURI)request.getRequestURI());
            // try to get destinationOrganizationSid from toUril
            destinationOrganizationSid = destinationOrganizationSid != null ? destinationOrganizationSid : getOrganizationSidBySipURIHost(storage, (SipURI)request.getTo().getURI());
        }

I have tried from RVD applications and customer RCML application and the patch is working.

The first patch was not working because the getMostOptimalIncomingPhoneNumber method is used by others SIP methods.
