I need to install hotdial phones onto public access premises.
I think that the best choice for security reasons is to use simple analog phones connected to ATAs.
And now the question.
How can I configure Cisco SCCP ATA for hotdial? (I know how to configure IP phone for hotdial but this configuration don't work with SCCP ATA)
How can I register Linksys SIP ATA on a Cisco CallManager? (I know how to configure it for a hotdial)
What version of sip are you using ?
