Latency between VXML gateway and Nuance server

[CSCO11598888]

Hello,

We were having Vxml gateway and Nuance server in same data center in the US, now we are working on data center migration so Vxml gateway and Nuance server are going to be in two different location in the US.

Could you please tell what would be the maximum latency ( round trip delay) between Vxml gateway and Nuance server so that latency shouldn't  impact our speech enabled  CVP IVR applications.

Thanks

That is a question for Nuance so you need to ask them, you will also need to know which Nuance product and what version.
