Call transfer (REFER) compatibility bug?

When a call initiated by PhonerLite receives a REFER from MicroSIP,  it responds with an ACCEPTED message and correctly initiates a new call but it doesn't  generate a NOTIFY (as required by RFC3515). This seems to result in MicroSIP failing to release the initial call properly.

RFC4488 allows the NOTIFY to be omitted if the REFER includes a refer-sub header - but this wasn't seen in my scenario.

PhonerLite supports REFER only in client mode. PhonerLite doesn't support to receive a transfer request. You need a server in between to support such transfer that handles such REFER.
