We have just moved to Australia and are getting an Australian Voip service in addition to the Vonage we have brought with us with our USA number. The Australian Voip provider asked which port does Vonage use as there could be a problem if it uses 5060 and only that port since that is the one their Voip ATA will use.

Doers Vonage use port 5060? Can it use another port? And if it can how do I switch it to another port?

According to Vonages web site, ports used are as follows ( http://www.vonage.com/help.php?article=1098&category=44&nav=3&refer_id=WEBTS0706010003W1) :

Ports used by Vonage Adapters

The following ports are needed for OUTGOING Internet communications from the Vonage device to the Vonage servers.

DNS: Port 53 UDP

TFTP: Port 21, 69, 2400 UDP

HTTP: Port 80 UDP

NTP: Port 123 UDP

SIP: Port 5061 UDP (used for older Vonage devices provisioned before 2005)

The following ports are needed for INCOMING and OUTGOING Internet communications from and to Vonage devices and servers.

RTP (Voice) Traffic: Ports 10000-20000 UDP. When a call is made, a random port between 10000 and 20000 is used for RTP (Voice) traffic. If any of these ports are blocked, you may experience one way or no audio.

Thanks for the info - clearly my search skills are not up to par since I tried searching the knowledge base and didn't find this info.

Looks like we're in the clear.
