[Asterisk-Users] UDP Fragmentation Problem

[Bastian Schern]

Hi everybody,

I've got no success to get a friend in Bogota (Colombia) connected to my 
Asterisk. 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 Asterisk not able to handle fragmented UDP packages?
Is it possible to use SIP over TCP with X-Lite?
Or has somebody another hint for me?

Regards
