Approx. 1 second delay at beginning of calls

Every time I make a call out, whoever answers the phone says "hello", but I never hear it. The inital 1 sec. or so of the conversation is cut off. We have QoS on the WAN interface (1721), and we do not use CCM. All 7940's with an SCCP load.

Thanks in advance for any help.

Have you tried with "voice rtp send-recv"?

Try to force "Early H245". In some cases media channels are negotiated after the CONNECT message.

Hi,

Please check whether you have the following commands-

voice rtp send-rcv

voice service voip

h323

call start fast

Let me know,
