Is it possible to use Cisco 5300 as a Pbx and at the same time use it for VOIP. If so please advice on the requirements both hardware and software. Urls as references will be highly appreciated
I do not know about the 5300 ,but it could be done with the MC3810.You could have a channel bank with 24 lines, attached to single line phones or trunks to it.
Not the easiest thing to do, but you get a dial tone and you will be able to make local calls, VOIP calls from the same phone.
Hope that helps!!!
Is there a reason why you want to use a 5300? (i.e. you have one lying around)
a 5300 can carry calls but it doesn’t have any of the features people expect from the PBX, such as call holding, call waiting, etc, etc…
A 5300 is just a gateway. If you want PBX features you need Cisco Callmanager at least one gateway. Callmanager can scale from a few users to 100,000s of users with Callmanager clusters.
This means it can be “right sized” for what you need.
Here’s a list of all of Cisco’s Voice software, Callmager is one of them and it interoperates with any H323 gateway. http://www.cisco.com/en/US/products/sw/voicesw/index.html
