[asterisk-users] ssh to a Cisco 7961 is not working

Sun Jan 15 16:03:30 CST 2012

Ken,

According with cisco docs, ssh is disable by default:

http://www.cisco.com/en/US/docs/voice_ip_comm/cuipph/firmware/9_2_1/english/release/notes/7900_921.html

SSH Access

The 
SSH Access settings option allows the administrator to enable or disable
 the SSH port on the phone using Cisco Unified CM Administration. When 
enabled, it allows the phone to accept the SSH connections. Disabling 
the SSH server functionality of the phone blocks the SSH access to the 
phone. This setting is disabled by default. 

This feature is supported on the following Cisco Unified IP Phones (SCCP and SIP):

•Cisco Unified IP Phone 7906G

•Cisco Unified IP Phone 7911G

•Cisco Unified IP Phone 7931G

•Cisco Unified IP Phone 7941G

•Cisco Unified IP Phone 7941G-GE

•Cisco Unified IP Phone 7942G

•Cisco Unified IP Phone 7945G

•Cisco Unified IP Phone 7961G

•Cisco Unified IP Phone 7961G-GE

•Cisco Unified IP Phone 7962G

•Cisco Unified IP Phone 7965G

•Cisco Unified IP Phone 7970G

•Cisco Unified IP Phone 7971G

•Cisco Unified IP Phone 7975G
