Hi Wes,
 
True.  I have a Microsoft Speech Server connected to our CM environment
(4.1.3) through a SIP trunk.  It works pretty nice.  We are looking at
IPICS, which from what I understand we will be using the SIP trunking as
well with this product.

Alan,

SIP trunk will only work to a proxy server.  it will not work for
endpoints.  CM5.0 adds SIP lineside support for to allow direct
registration of SIP clients and adds the ability for CM to function as a
SIP back to back user agent.

	Hi Wes,
	 
	I just have a question regarding CCM 4.0 intergrated with SIP, I
see lots of document say that CCM5.0 is fully compatible with SIP, but
can I do it in CCM 4.0 by using SIP trunk?
	My customer is looking for a soultion that some of the users in
organization will use SIP phone and others will use Cisco IP Phone, is
it possible to deploy this solution in CCM 4.0? I have tried to
configure CCM working with MS Office Communicator (act like SIP
softphone), not worked well, I can see incoming call from Office
Communicator but can't answer it. 
	 
	Thanks so much.

		I have not used the Vail Systems SIP TIM but the CM SIP
trunk is pretty
		basic.   Configure it with a destination address = IP
address of your 
		destination device, set the port number (5060 by
default), select TCP or
		UDP, check the box for MTP required (note default CM MTP
resources are
		g711 only..  you will need hardware DSP resources for
g729)
		
		then create a route pattern pointing to the SIP trunk.
give it a
		partition if desired. give your originating device a
calling search
		space that includes that partition.
		
		I have been testing the SIP trunk last few weeks and it
seems to work well.
