[Asterisk-Dev] no 1xx messages following reinvite with authentication

[Alex Zeffertt]

On a related note....

I'm having a problem with SIP authentication.  When my UA INVITEs
Asterisk I get the following exchange:

	UA					Asterisk
		-INVITE----------->
		<-407 Auth reqd--
		-ACK--------------->
		-INVITE+auth---->
		-INVITE+auth---->
		-INVITE+auth---->
		-INVITE+auth---->
	            ....
		<-200 OK---------- (other end goes off-hook)
		-ACK--------------->

The problem is that the UA never gets an informative 1xx response to its
INVITE+auth message.

This means that the UA can only assume that Asterisk has not received
the INVITE+auth and it keeps retransmitting it.  It also means that the
UA cannot generate an appropriate progress tone, e.g. a ring tone.

Why doesn't Asterisk generate a "100 Trying"  or "180 Ringing" message
when using authentication?
