Can I know what are the considerations when selecting from the different models of ASA currently we are debating if we should buy a 5510 or a 5520 also can I know if cisco ASA also have a limitations on concurrent users online in a lan like our old firewall. By the way we are a Call Center company(going 500 seats) so we are using VOIP(Asterisk using SIP and IAX). Thanks for the support</P> Mon, 11 Mar 2019 20:30:01 GMT toskie9999 2019-03-11T20:30:01Z https://community.cisco.com/t5/network-security/asa-model-selection/m-p/1705452#M563075 <P>Hi All</P><P></P><P>&nbsp;&nbsp;&nbsp;&nbsp; Our company is in the process of replacing our old firewall with a Cisco ASA since our old firewall can handle only 170 concurrent users and we are expanding fast.
