Setting the VIA field in SIP registration?

[PrinceAlbertz]

Hi,

Anyone know if this is possible using the sip profile registry? If not is it the case that CSIPRegistration has to be used?

I thought CSIPMessageElements might be the class to use, but it seems that it cannot be used after all (From the API reference):-

The class does not allow you to create SIP headers that MUST only be created and manipulated by the SIP Stack. I.e. SIPHeaderBase::Name() != ("Authentication-Info" || "Call-Id" || "CSeq" || "From" || "Max-Forwards" || "Min-Expires" || "Record-Route" || "Security-Verify" || "Service-Route" || "To" || "Via")

Thanks
