When I connect to a mobile or cell phone from my Cisco ATA191 there is a 2 second delay between what one party says to the other party receiving a reply - which ATA191 settings should I check and/or modify to correct this? Landline to landline calls are fine.
Do you mean the sound is delayed by 2 seconds ? No, you can't configure it as such delay is not caused by ATA191. It's networking issue - the SIP packets are delayed in transmit. Ask your network guru for help.
