Endian with SPA922 IP phone - won't ring

[Guest]

Hi,

I'm kind of new to this stuff so bear with me if this is a really elementary question. I have a set of VoIP phones here (linksys SPA922) and they are registering and have dial tone but do not ring in/out. I have the appropriate ports opened (according to documentation, UDP 5060-5090 plus 16384 - 16482). We had them on the BLUE network at once time; I noticed that the 5060-5090 ports were configured but then there was an outbound ALL as well. There was no SIP proxy set up.

When I configure ALL outbound UDP on the green network, the phones ring normally. But obviously we do not want that configuration...
Any ideas? I think the person who set up the blue network also gave up else he'd probably not have opened all the ports...

Thanks.

Based on the ports you mention, I am assuming you are using the Vonage Hosted VoIP Service(s).  If so, I recently also had to configure an EFW system for Vonage and I was able to get it working smoothly with either of the following . . . .

Option 1:
Ports To Be Allowed From Phone Adapter/Router or 'Zone'
UDP/21
UDP/69
UDP/80
UDP/123
UDP/2400
UDP/5060:5061
UDP/10000:20000
UDP/62265

Option 2:
Allow all outbound ports/services from Phone Adapter/Router or 'Zone' to Vonage IP Address Subnets
216.115.16.0/20
69.59.224.0/19

ie: from 'green' to ip/subnet (above) service/port any

Should work with either of the above.

Good Luck,

Took a quick look at the firewall logs on my EFW box - if you use the 'ports', change the 10000:20000 to your 16384 - 16482 so that you don't have to open that whole range of udp ports.  The efw box I have is using port 16723, so I theoretically could shorten my range to about 16700:16800 and it should still work correctly.

The 2nd option is probably the best to limit those ports only to the vonage destination servers.

Your responses are quite helpful although we are using RingCentral instead of Vonage. I tried the 2nd option and got everything sorted -- we now can call in and out without a problem.

Thank you SO much for your assistance!

Good post!
Allow me to add.

I use callcentric and for them my setup is:

VoIP adapter (SPA3201) on Orange interface. Currently the only use of Orange.
Open Ports:
ICMP 8/30
TCP/UDP 53
UDP 123
UDP 5060:5080
UDP 16384:16482
