I'm attempting to register a SPA112 to our Alcatel OmniPCX enterprise PBX. When attempting to register the SPA112, the PBX returns a 501 Not Implemented.
Register message from SPA112:

Once authenticated I can go on to make calls, all of which work successfully. The SPA112 is unable to connect however.
Given that the differences in headers are minimal, I'm guessing that the PBX doesn't know what to do with the P-Station-Name. Is there a workaround or a way to disable the header from being sent in the REGISTER message?
