For Cisco Ip telephony when using IP Phones CCM or VG we use a predefined range UDP ports in the range 16384 to 32764.

That would be the recommended I think

If more users join, does it mean that need to expand the UDP port range? Thank you

VoIP UDP ports (RTP) should be the same, it?s doesn?t matter what vendor or voip protocol you are implemented unless the vendor itself specify it.

What you mean when you mention ?if more users join?

The range is from 16384 to 32764.

Don?t forget to open the Signaling TCP port.

Best regards.
