In any consultative transfer (IIRC, you're doing a consultative transfer), there are three SIP "User Agents" (UAs) participating. Colloquially, UAs are called "phones" but of course, they can be "the other end" of a VoIP provider, or whatever. In order for the consultative transfer to be completed successfully, each of the three UAs needs to execute the correct SIP operations. So if any one of them does not implement the features that are needed in its role, or refuses to execute a feature at the moment it is needed, the consultative transfer *will* fail. There is no workaround, any more than there is a workaround if one wheel of a motorcycle is missing. What you are describing is that one of the UAs, when it receives the REFER, responds 603. So the consultative transfer *cannot* work in this environment. If you wish to continue testing your UA, you should to replace this UA with one that implements the needed features.
