Believe me, we have fought long and hard with this customer tom make him understand that SCCP is where he should stay but the aggresive stance he has taken towards SIP makes me believe there are ulterior motives for him to push for SIP so we have to move these to SIP even at the cost of features.<br><br>At this point there is no convinving statement in this MIS Manager's mind to stay with Skinny.<br><br>Jorge

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>
<br>All you'll get is a warm fuzzy feeling and higher long term support costs.<br><br>If there is no mandate from on high to use SIP - then stick with SCCP.<br><br><br><div class="gmail_quote">On Wed, Dec 17, 2008 at 9:54 AM, Jorge L.

<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>
