Hi,
We have separate SSID for data and voip in our wireless network.
I have connected my laptop to wi-phone SSID and gave a ping to other laptop IP on same SSID. The round trip time is around 707ms. Sometimes it is reaching more than 1000 ms.
When i connect to my data SSID, the round trip time is very very less around 3 tp 4 ms.
When I try to ping to a phone which is on call, the round trip time is around 50 ms.
Please suggest on how to resolve this issue. Please let me know, if any configuration related information is required.
Regards,

it could be due to power-save enabled on those laptops. Disable it and try.
disable/enable wmm on laptop and try.
Try pinging the phone at off call you may experience high RTT when it is not on call.
ping on WLC is handled as best effort. try file transfer or iperf/jperf.
what's the client(s) rssi and snr when you test.
If the above didn't help check config between the WLANs in question.
