SCCP. You should only use SIP if you’re using non-Cisco IP phones. IMHO,
Cisco is behind the times and should be pushing SIP more aggressively on their

<p class=MsoNormal style='margin-bottom:12.0pt'>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>

<p>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 lang=ES><o:p></o:p></span></p>
