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

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).

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.
