Can Asterisk server and ATA active on same network?


I currently use VoIP via an ATA. If I want to experiment with Asterisk, can both be active on the same network? I may take a while to clear the learning curve of Asterisk, I would like to continue to use the ATA as the main way to use the phone.

Thanks in advance for any help.

Providing they use different IP addresses or SIP port numbers and RTP port ranges, they can co-exist.
