Just update my test FS to newest snapshot: FreeSWITCH Version 1.0.head

(git-5310735 2011-04-07 15-47-30 -0500)

I am using SJphone softphone to call into my test FS1. This FS1 then forward

the call to another FS2.

FS2 will answer the call and start Music On Hold.  Basically I am using

SJphone to initiate a SIP call  and let FS2 to answer the call with Music On

Hold.

It is working with older version of FS. Now after update to this newest

version. The call sometime will not go through. The SJPhone just keep

ringing until timeout. This happens maybe on half of the calls. I also tried

to use Asterisk to replace FS2 for Music On Hold and it did the same thing.

The following is the part of console sofia log info:
