It maybe a small nuance, but as a CCM administrator I can understand the refusal to support a roaming H323 or SIP endpoint on CCM. Perhaps if your asterisk box was not mobile, the CCM admins would consider a H323 trunk to your system? > I've read that Asterisk supports SCCP, at least somewhat.

The SCCP support in Asterisk is currently limited to asking as a SCCP server, not as an SCCP client. So you cannot use Asterisk to register as a phone to CCM. The SCCP protocol does have a 'trunking' mode, but Cisco barely uses it themselves, and it is geared to low density situation, two-four channels. I am not aware on any effort to duplicate that in chan_skinny. It is conceivable that chan_skinny could be taught to emulate a Cisco endpoint (7965 for example), but the end result would be of limited value. It would have a limited number of lines/channels and the protocol in this use model would not support passing destination information, so it would require a 1-to-1 mapping of a CCM extension to an Asterisk extension. > I heard that one of the problems in interfacing with CCM over SCCP is the use > of proprietary codecs. Would this be a problem in my case? Not quite true. SCCP is a proprietary protocol, but the codecs supported match well with what Asterisk offers, at least the codecs you would likely choose to use. > If there's a chance it can be made to work, I'll give it a try.
