I need to ask: When you talk about forwarding the ports, are you talking about the ports on my router? If so, I see no RTP options.
None of these suggestions may resolve your issue, however I suspect that you may not have covered some of the more basic trouble shooting
steps.You did not give any specifics about your particular setup. You should mention the router brand/model. Is the call GV<->PSTN, GV<->sip, GV<->GV?
FAQ ( http://www.obihai.com/FAQ.html ) These should cover all the ports for an OBi110/100. The OBi202 has additional RTP ports to open. (SP3+SP4)
What ports should I keep open on my router/firewall?
In order for your OBi to be able to send packets w/o interruption, please configure your router as follows:
Allow Outgoing:
TCP Ports: 6800, 5222, 5223
UDP Ports: 5060, 5061, 10000 to 11000, 16600 to 16998, 19305
Allow Incoming on UDP Port: 10000 Additional troubleshooting steps in the event you decide to set up a sip account and encounter one way audio.1) Try to disable the sip ALG setting in the router. In many routers this breaks sip. In your case you mentioned using GV. GV does not use a sip protocol, so I don't expect it to fix the issue. This is more a preventative measure for when you setup a sip account in the future.
2) Set up a Stun server. A stun server helps the router and the ATAs (OBi) in the communication to negogiate the WAN ip (internet) address and port numbers of the call automatically using the sip protocol. Note that once again this is developed for sip clients. In the case of GV I don't expect it to resolve one way audio.
Have a look here for port forwarding info. (
http://portforward.com/ )You should find info specificly related to your router brand. You will not find any reference to RTP in the router itself. The RTP ports are used to pass the voice part of the conversation. On the OBi you will find the specific port numbers to forward where I indicated with the arrow. They above ports from the FAQ is more complete.
This should keep you busy for awhile.
