Hi all

Can somebody explain me the considerations of internet bandwidth regarding connecting several remote users with cisco ip softphone?

How much bandwidth typically i need for each user who is using cisco vpn client and ip softphone in terms of download and upload?

Does the same considerations applies for branches with cisco IP Phones connected via branch VPN router?

Thanks

The Cisco VPN client will try and use as much bandwidth as possible, so it will depend on what you are planning on doing other than the SoftPhone. Also make sure you enable QoS and have that setup properly, otherwise you will have bad call quality.

A typical g711 call will use 87.2kbps including IP overhead, so you need to make sure you have enough bandwidth for the number of calls you want to process. Otherwise you could try using the g729 codec which would use 31.2kbps. Have a look at this document http://www.cisco.com/en/US/tech/tk652/tk698/technologies_tech_note09186a0080094ae2.shtml

For the branch site with IP Phones via VPN it is the same consideration, how many Phones? How many simultaneous calls? What other network applications are going through this? And again QoS configured properly is paramount!
