Summary:                    [patch] Problem with dialing SIP peer that is not
reachable.
Description: 
I am using:

*CLI> core show version
Asterisk 1.8.1.1 built by root @ asterisk on a i686 running Linux on
2010-12-17 23:03:58 UTC

I have some problem with DIal() to SIP unreachable friend.

My dialplan:

exten => _XXXX,1,Dial(SIP/${EXTEN},60,rt)

Now, when I Dial extension 1050, and there is no 1050 peer registered I
got:

[Dec 18 22:51:04] WARNING[2307] chan_sip.c: sip_xmit of 0xc2e1330 (len
843) to 0.0.4.26:5060 returned -1: Invalid argument

@pabelanger,

Much much better v3 is. There is a 5 second silence before it say Invalid
extension :)  

But in asterisk 1.2 and 1.4 has only 1 or 2 second to declare invalid
extension. 

Now i am getting following error "ERROR[12988]" RED keyword sometime looks
scary to me :( can we change it to WARNING :) 

[Apr 29 10:08:44] ERROR[12988]: netsock2.c:263 ast_sockaddr_resolve:
