hi,
I m using ser-0.8.14.
i m trying to send a SIP message from an SER server to another SER server. The length
of this message is greater than 1500 Bytes(around 1600 Bytes) , so it is fragmented
before being sent.
(in my case it's fragmented to 2 packets.)
then I check the SIP flow using ethereal I found that :
In the IP header of the first packet, the "more fragment" flag is set to
"0" so at the reception the second packet is ignored.
And we get at the receiver a SIP message which is not completed.( we don t receive all
the SIP message).
is it SER who force that the sent message being less than 1500 bytes ?
thinks a lot

Are you sending your message through UDP or TCP?

Hi,
IMHO it has nothing to do with SER.
I've experienced this before.
Check your MTU, your network and firewalls.
Limit size of SIP message by consume_credentials() and limit number of
codecs used.

my request goes through many SER servers( more than 5 and in the future it can be much
more ) and each one add headers before forwarding the message. So I prefered not to put
any constraint on SIP request size.
I will check the MTU and my network. but I m not sure that the problem is in the
network because when I send a PING "message" greater than 1500 byte, it is
sent without problem (the message is fragmented and the "more fragment" flag
of the first paquest is set to 1 so at the end we get a complete message).
