[asterisk-users] Alcatel OXO Sip

[Christian Gatti]

It the question why does asterisk has problems with SIP/2.0/udp or
SIP/2.0/UDP

if (strcasecmp(via, "SIP/2.0/UDP")) {
	ast_log(LOG_WARNING, "Don't know how to respond via '%s'\n", via);
	return -1;
}

This code says: I don't know what to do with a SIP/2.0/UDP in a via and
blocks (return -1).

Should the alcatel pbx not send something like SIP/2.0/udp in a via?

Christian

Oops! Yes, I was confusing strcmp and strcasecmp, sorry - too little coffee.

However, it's funny that the strcasecmp of "SIP/2.0/UDP" fails to match with
"SIP/2.0/udp". Almost like it's using a strcmp instead of strcasecmp!
