<DIV>Thanks for your input Raúl.</DIV>
<DIV> </DIV>
<DIV>in the packet captures, I notice following items:</DIV>
<DIV>INVITE sip:1xxxxxxxxxx@sip.voipstunt.com SIP/2.0<BR>Record-Route: <sip:x.x.x.115;r2=on;lr=on;ftag=3F30077D-570BCE0A000B61B3-54909700;ngcplb=yes><BR>Record-Route: <sip:127.0.0.1;r2=on;lr=on;ftag=3F30077D-570BCE0A000B61B3-54909700;ngcplb=yes><BR>Via: SIP/2.0/UDP x.x.x.115;branch=z9hG4bK037e.d0ff913568a8906a194cc8f2492a77c7.0<BR>Via: SIP/2.0/UDP 127.0.0.1:5080;received=127.0.0.1;branch=z9hG4bKsdiM4aEk;rport=5080</DIV>
<DIV> </DIV>
<DIV>I wonder if the 2nd record-route message and 2nd Via message are necessary. If they are omitted, the sip packet won't be fragmented.</DIV>

<DIV>Hi, gang,</DIV>
<DIV> </DIV>
<DIV>Is there a way to shrink the header of sip message sent from spce? I configured a <SPAN id=x761f1c3b6ea84d86ada77d3cd52807cc>sip trunk with </SPAN>VoIPStunt as a test. After receiving invite message, VoIPStunt sends 401, spce then sends out an sdp, supposedly containing authentication digest, however, the message gets fragmented. VoIPStung never responds again, apparently it doesn't assemble fragmented packets.</DIV>
<DIV> </DIV>
<DIV>I then change the trunk's transport protocol to tcp, VoIPStunt doesn't respond at all, I guess it doesn't support tcp.</DIV>
<DIV> </DIV>
<DIV>spce version is v4.2.1. in the attached screenshot, 77.72.169.129 is VoIPStunt's ip address, the other is my spce's.</DIV>
<DIV> </DIV>
<DIV>thanks,</DIV>
<DIV> </DIV>
