Re: audo delay from remote site to central site

Jason, there is no IVR but straight passthrough of the call to the agent ? Is IPCC installed with g729 installed or is there a transcoder involved ?

Re: audo delay from remote site to central site

IPCC Express 4.0(3) was setup/installed for G.729a. No transcoder is being used as IOS Gateway/7900 Phones can doing G.729a/G.711 without a transcoder. Changing from G729a to G711 requires running setup again.

Additional testing show IP Phone to CTI Route Point to Agent has same delay, this eliminates the Gateway IOS as the issue. Put Agent in G711 device pool and same issue. Suspect if I changed IPCC and prompts to G.711 this would go away!
