> Found a VOIP provider failed to authenticate account after upgrade to 1.8.3 from 1.6.1.
> Traced SIP packet, found an extra non-readable character following Contact header, inside the 2nd INVITE with md5 digest responded to 401 from provider proxy. The first INVITE is ok though. Didn't find smilar issue reported by google search or forum search.
> I'm not a developer, but a system admin, so not an expert on coding. Took me several days found the code that missing a line for MIPS (SPARC) platform. I'm using * on the router with Openwrt. Thus everybody else using it on X86 should be ok. 
> I think it might better to report it so it would help for those who use it on SPARC or MIPS. Checked 1.8.4 code still unchanged.
