I have 2901 router with ISM-SRE-300-K9 module for CUE.
I am trying to install cue 8.6 on this module as the cue boots in bootloader I am following the procedure as listed in http://www.cisco.com/en/US/docs/voice_ip_comm/unity_exp/rel8_6/install/boothelp.html
but as the installation progresses after the language selection the cue comes with an error of Curl Code Error 19 Error Dowloading Payload.
It would be really helpful if someone could find a solution for this problem. I have tried with diff IOS with supporting CUE’s, I tried with diff FTP servers as was listed in a forum but results in same error.
