[Asterisk-Dev] Again: 7920 Cisco IP Phone Skinny & SIP

[Jan Czmok]

hi!

i had some good news regarding the cisco 7920 and the internetworking
with asterisk (and possibly SIP ?).

Status: chan_sccp.so not coredumping anymore :-)
	Phone contantly in reboot loop [see below] :-(

Reboot Loop means:
------------------
 Phone auth's with AP
 Phone gets IP from DHCP & TFTP Server
 Phone loads OS7920.TXT
 Phone loads SEP<macaddr>.CNF.XML
 Phone loads xmlDefault.conf.xml
 Phone registeres to Asterisk
 Phone gets registered
 Phone gets Info/Dial/Stuff from Asterisk
 Phone gets Line Info
 SKINNY LineStatReqMessage
 SKINNY LineStatMessage
 SKINNY LineStatReqMessage
 SKINNY LineStatMessage
 SKINNY LineStatReqMessage
 SKINNY LineStatMessage
 SKINNY LineStatReqMessage
 SKINNY LineStatMessage
 SKINNY LineStatReqMessage
 SKINNY LineStatMessage
 SKINNY SoftKeySetReqMessage
 SKINNY SoftKeySetResMessage
 SKINNY OffHookMessage
 SKINNY SetSpeakerModeMessage
 SKINNY OnHookMessage
 SKINNY DisplayPromptStatusMessage

 SKINNY DisplayPromptStatusMessage

But if you look at the Support of the 7920 in Callmanager Express, you
get a file named "cmterm_7920.3.3-01-02-021.bin" so i was investigating
further. so i wrote "cmterm_7920.3.3-01-02-021" in OS7920.TXT and
suddenly the Cisco 7920 shows "Upgrading Firmware" :-)
Unfortunately for some reason it did not accept the firmware, but it
still tries to load it. 

Some additional info:
---------------------
The 7920 is requesting cmterm_7920.3.3-01-02-021^J.bin
(so with an Ctrl-J in it), so you have to rename the file.

I also got the information from documents that the 7920 is running in
7960 emulation mode, so draw your own conclusions in regards of SIP
possiblity :-)

I tried to use some 7960 images, but did not succeed :-(

Would appreciate some help in this issue :-)
