asterisk users - Jan 2005 - Polycom IP 300/500 Conferencing Behavior

Hello,
	I've got a mixture of SPIP 300 and 500 phones in production for 
various clients. I've got the XML settings configured for local 
conferencing, but I'm not seeing the expected behavior from the phone when 
I attempt to conference two calls together. According to the manual, while 
talking to the first party, you simply hit Conference, dial the second 
party and then Conference to join them. This is supposed to put the first 
party on Hold until you bridge them together with the second press of the 
Conference button.
	That is all fine and well, but it doesn't quite work the way that 
the manual describes. Instead of joining the two calls together when the 
Conference key is pressed for the second time, the first party is taken 
off hold and hears dead silence. The only way to correctly join the 
parties is to hit the Hold and then Resume soft key, at which point all 
three parties can talk to each other.

As an illustration

Conf -> Dial -> Conf doesn't work.

However,

Conf -> Dial -> Conf -> Hold -> Resume DOES work.

	I'm running 1.3.4 firmware on all the phones, and I can't for the 
life of me figure out what is causing this problem. It is very likely some 
misconfiguration in the XML files, but I can't find it. Anyone have any 
suggestions?

Hello,
	I just thought I would follow-up on this post and mention that 
somwhere between Jan 21st and today, the Conferencing issue that I 
described below is no longer an issue. Normally, I wouldn't include the 
entire quoted context of the message for bandwidth reasons, but in this 
case, since the topic is nearly 2 months old, I figured it would be 
helpful to keep things consistent and on-thread.

	I'm not sure what may have been fixed. I.E. I don't know if it was 
a patch to chan_sip in stable or what. All I can tell you is that I 
haven't made a single change to either sip.conf or my XML config files, 
since the original posting in January. However, I have updated asterisk 
several times from the 1.0 branch.

I'm happy that this is fixed, but I am going to do a little more reasearch 
to see if I can get it to fail again by backdating chan_sip and 
incrementing it forward.

This should be interesting. :)
