This is expected behavior for SIP communications.  I see this all the time
when an end point is registering with Asterisk.  I think in those cases,
however, it's a REGISTER request, not an INVITE.  How is your sip.conf
configured for these end points?

Do you have any phones other than the ones experiencing this problem that
you can test with?
