Hi everybody,

I've got no success to get a friend in Bogota (Colombia) connected to my SER. He has got a ISDN Internet connection and the UDP packets will be fragmented. It seems that the MTU of this connection is round about 400 to 500 Bytes. Therefore most UDP-SIP packages are fragmented. Is SER not able to handle fragmented UDP packages?

The packets are defragmented by the ip stack of the OS, so ser doesn't really care if they arrive fragmented or not.

Is it possible to use SIP over TCP with X-Lite? Or has somebody another hint for me?

If you plan to use TCP, keep in mind that nat traversal won't work (if you use it).
