How do I configure a CM that will have ATAs and IP phones other than Cisco? for instance a CM with 700 non cisco extensions and one Cisco Gateway with two E1 and one non Cisco Gateway with 2 E1s.
Im not sure what exactly you want to configure
Normally with E1 you configure Voice termination, Could you please clarify
Other than Cisco IP Phones you can use Avaya IP Phones with CCM. Those will work fine.
Rate the solution if it works.
