I have an Avaya Index in London, we are opening a new office in Orlando. I understand VCM channels and will have a 2meg SDSL in London and a 3meg direct circuit in Orlando. I will have 20 users in orlando taking inbound calls from London and making outbound calls on the London switch. What is needed for QOS. Is it my ISP or hardware or routers??
 
Possibly all 3

VOIP datastreams contain the QoS information.

Any hardware which the VOIP data packets passsthru MUST have Qos enabled.

Some ISP's provide guranteed time delays across their infrastructures.

Avaya sell a VPN device which has Qos features.

Without QoS call reliabilty & Quality will be unacceptable based on my experiances with ADSL based VPN links.
 
I have question regarding VPN. IP Office (2.1) has integrated VPN capability and I noticed that it has limited VoIP tunnels, only 4 (403,406 & SOE)
Only 412 has 10 tunnels capacity...

If I use external VPN device then I can have more than 4 tunnels on IP403 (probably depends on VPN device), right?
