We have an ASA 5520 in place as firewall/rotuer/vpn. We will be adding a Cisco UC520 to our network. I am new ot the UC520 and VOIP .
Can the UC520 stay behind the ASA and still use a SIP gateway service. Does that create issues down the road. I know the UC520 also has firewall/vpn/routing , but not sure if that is going to cause issues.
What had to be done on the ASA and also the UC520 for them to work on the network?
