[cisco-voip] Delayed audio-cutover with H.323 gateway

[Erick Bergquist]

4 to 8ms on average. Fast start not enabled on GW - let me look into that.

What is round trip time from gateway to CM?  Are you using fast start  
on CM and the gateway?

Hi,

I'm having a issue where an inbound call comes in FXO port and  
connection plar's to a shared DN across 5 IP Phones. The phone call  
gets answered fine, but the user on IP phone saids "Welcome to  
BlahBlah" and the outside caller doesn't hear the first time they say  
"Welcome To BlahBlah" and the IP Phone user repeats their greeting  
and they hear it the second time fine.

There are no errors on any interfaces that I can see, and the gateway  
has voice rtp send-recv enabled. Issue does not happen on calls over  
PRI, just the analog FXOs. I have disabled caller-id on the voice- 
port and also tried connection plar opx with no difference. Sometimes  
it works fine but rarely.

CCM is version 4.1(3)sr3c and the gateway is a 1760 running 12.4(8a).

A similar problem can happen when the call is parked or put on hold  
also, now and then.
