I don't really recommend moving to SIP on your IP Phones. From my personal experiences, these phones "just work" with SCCP. With SIP there are so many "gotchas" and caveats that I wouldn't think it is worth the hassle just to use "Open Standards".<br>

<p><span lang="EN-US">I have a Customer that wants to start
moving to Open Standards and wants to move his phones which support SIP to SIP
and leave the older not supported models on Skinny until he starts replacing
them with newer models. I see that there is a CCM SIP image for the 7940/60. Is
there anything special needed to support these phones on the CCM as you need
with native SIP phones like say Linksys or do they just behave like their skinny
based counterparts? I guess my question is, do I still need to use stuff like
the NTP reference instead of the CCM time group or create special MTPs for these
phones as I would need for other SIP devices? Also I see there is a CCM SIP
image as well for the 7912 but it says CCM 5.0.4 only, has anyone tested this
fw with ccm 6.1.2?</span></p>
