Delayed voice for attendant console - H.323 gateways

I have had a customer with attendant console mention that it takes a little while for the voice to be heard when answering the call. CCM 3.3(2)SPC and using 2651XM gateways running H.323, ISDN PRIs. I was looking at a few other conversations on this forum and saw a mention of some H.323 timers that could possibly be tuned.

The H.323 faststart inbound option. Would this help? I am reluctant to change things like this with the amount of users on the system as other than this the network is AOK.

Any suggestions?


Re: Delayed voice for attendant console - H.323 gateways

Have a look under the CM service parameters and if necessary, set the option "H323 FastStart Inbound" to True.

This will often fix slow audio cutthrough problems on H323 gateways.

Also, make sure the gateway has the command 'voice rtp send-recv' configured as well.

Thanks Paul... just wanted to make sure there were no adverse affects if I put it on. And voice ctp send-recv is definitely on.
