Howto monitor a CTI link

Hello,
I’m looking for a solution to monitore a CTI link between Asterisk and CTI client appalication; so that as soon as the link is dead of freezed, i can receive a mail. I’m actually checking Zabbix and Nagios, but i’m not quite sure that they will help.
Thanks if you have any idea.
Brgds.

Please try again on the right forum. Probably Asterisk Support.
