allow only voice call

To allow only voice call, do we only need to allow udp port range from 16384 to 32767.

Is there any other tcp port that should we allow?

Re: allow only voice call

If you allow 16384 to 32767, you'll alow th enitre rtp range

covering both voice , audio and video.

For voice only in cisco devices use the port below..

16383 & 16384 for rtp sreams and also

11000 - 11999; for H.245 port numbers

1718-1719 for ras

1720 for h225

This would allow both signalling and rtp media stream for vocie only.
