Asterisk SCCP channels
SCCP channel drivers in Asterisk
There are 2 variants of SCCP channel drivers which exist for the Asterisk PBX:
Supplied driver with Asterisk
- chan_skinny or Asterisk channel skinny The "original" Driver written by Jeremy McNamara & Florian Overkamp
Alternative implementations (not in the Asterisk CVS)
- chan-sccp-b (for Asterisk 1.4 and 1.2): http://sourceforge.net/projects/chan-sccp-b
- chan_sccp2: Proven sccp driver for Asterisk 1.2.
- An alternative Implementation of the SCCP driver by Theo Zourzouvillys (see also http://crazygreek.co.uk/content/chan_sccp )
Sample setups for SCCP
(for the chan_sccp drivers):
- SCCP-HOWTO1 Generic Notes about the chan_sccp implementations
- SCCP-HOWTO2 Setup your Asterisk to work with Cisco 7920
Various other projects exists at sourceforge.net but only these 3 are working only with some devices
(not all SCCP devices are supported by every driver)

333Having problem with Cisco IP Communicator
I did patch the SCCP to my Asterisk. SCCP version is 20051209. When I want to use my Cisco IP Communicator, Debug shows me the following lines:
-- SCCP: Accepted connection from 217.219.24.159
— SCCP: Using ip 217.219.24.240
— SCCP: >> Got message RegisterMessage
— SEP000EA62CA2AE: is registering, Instance: 0, Type: Cisco_IP_Communicator (30016), Version: 4
— SEP000EA62CA2AE: Rejecting device: Ip address denied
Can anyone help me?
Thank you.
333Cisco 7910
i follow the steps for config the support SCCP with the asterisk. And i configurate the files SCCP and Extensions and the phone Work.
BUT i’m using cisco phone 7910 and every time I call someone and that person hung up before me the phone gets blocked. But when the person I’m talking to hung up after me the phone doesn’t get blocked.
Do you have registered a problem like the one I exposed before, do you have reached a solution? Would you be kind enough to write to me and explain the solution.
Thanks
