Re: [SR-Users] truncating sip message

Hello;     I saw it. it is fragmented IP and cant resolve it wireshark. But i cant understand one thing, First Call Flows makes fragmantion but second call flows doesnt fragmantaion even if it is larger than first call flows.

Maybe they are not truncated by rather fragmented.  If you are capturing packets by UDP Port you will not see the fragments.  Try to capture again by IP only and you will see all packets.     i tried to remove all extra addes  , include Record-Route and send messsage , no truncate. and then started to add headers and BOOM. after 5 headers , it is truncated. configuration become simple to testing one by one. i couldnt find way to solve it.     i tried to sniff with tcpdump and sdp body result here , truncated.; Call Flows --- UAC1 --&gt; Kamailio1---&gt;kamailio2--&gt;UAC2  --truncated sdp body UAC1 --&gt; Kamailio2---&gt;UAC2              --No problem Destination ip tcpdump: host-kamailio2ip.sip-tls &gt; uac2ip.sip: SIP, length: 1472         INVITE sip:1021uac2num@uac2ip:5060 SIP/2.0         Via: SIP/2.0/UDP kamailio2ip:5061;branch=z9hG4bK61c7.f5edc3dbd9effe58f3d04a6b77b11f13.0         Via: SIP/2.0/UDP kamailio1:5061;rport=5061;branch=z9hG4bK61c7.189d12e4e39ec53abb760692e8a8afee.0         Via: SIP/2.0/UDP 192.168.0.225:10251;received=uac1ip;branch=z9hG4bK702835784163333;rport=17762         From: uac1 &lt;sip:uac1@kamailio1:5061&gt;;tag=1848614912         To: "0uac2num" &lt;sip:0uac2num@kamailio1;user=phone&gt;         Call-ID: 228601536217236-500684316713@uac1ip         CSeq: 2 INVITE         Contact: &lt;sip:uac1@uac1ip:17762&gt;         Proxy-Authorization: Digest username="uac1", realm="kamailio1", nonce="Vwd5PlcHeBLSAh0pqSU3AvKzvNAD+QGC", uri="sip:0uac2num@kamailio1;user=phone", response="d296105a65958144cf1b60c921aef11b", algorithm=MD5         Max-Forwards: 68         Supported: replaces, join, path         User-Agent: Fanvil C58/C58P 2.2.41.13         Allow: INVITE, ACK, OPTIONS, BYE, CANCEL, REFER, NOTIFY, INFO, PRACK, UPDATE, MESSAGE         Content-Type: application/sdp         Content-Length: 276         P-Provider:kamailio1         P-Unique:srid-5707759b-29c4-1         atik:1231345123         atik2:1231345123         atik3:1231345123         atik4:1231345123         atik5:1231345123         v=0         o=8503027337 2007313085 1038110647 IN IP4 192.168.0.225         s=A conversation         c=IN IP4 192.168.0.225         t=0 0         m=audio 10208 RTP/AVP 8 0 18 101         a=rtpmap:8 PCMA/8000         a=rtpmap:0 PCMU/8000         a=rtpmap:18 G729/8000         a=rtpmap:101 telephone-event/8000         a=fmtp:1[|sip] 08.04.2016 12:03 tarihinde Daniel-Constantin Mierla-6 [via SIP Router] yazdı: Hello, how did you asserted the fact that the message is truncated? Is the next SIP hop not retrieving it with full content? Or just you looked at some traces on the net, if this one, note that some network sniffing tools are having their limitations in what they display.

What do you mean by remove_hf() is not working? How you try it? Can you send here how you use remove_hf() in config and the incoming, plus the outgoing sip message?
