Simply Ser does not recognize, that 192.168.1.240 is its local name (probably
because that IP is not resolvable via DNS). And, for whatever reason, you
deactivated the maximum forward check. Thus the INVITE is forward in an
endless loop to Ser itself (you can probably see that if you sniff on the
loopback interface). Finaly the request is probably getting so big, that Ser
is getting out of (local) memory.
1. activate the maximxum forward check in the begining of your route section.
Then you should receive "483 Too Many Hops" instead of the 500.
2. add 'alias = 192.168.1.240' to your global config section, then Ser should
recognize that the request is for the local proxy (and you will probably
receive 404, because your phone is not regeistered)
