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.<br>

<div>Hi Wes,</div>
<div> </div>
<div>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?</div>
<div>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. </div>

<div>Thanks so much.</div>

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