Error handling the provisional 100-Trying replies to INVITE in OpenSER v1.2.0 with two interfaces

Instead of treating 100-Trying hop-by-hope the SIP server retransmits the 100-Trying back to the SIP phone. The SIP server also does not recognize the fact that the 100-Trying is replied by the next proxy due to the received INVITE and retransmits the INVITE as if it was lost:

The PDF file contains the contents of each of the shown 29 messages. Each page of the PDF file represents one message [pdf], [ps], [txt].

The SIP server listens on two IP addresses: 192.168.1.15 and 128.179.67.76.

The SIP phone is located at 192.168.1.10.

Is it a bug in OpenSER?
