Connecting VoIP with IP PBX
Is there a workable solution for VoIP long distance with companies such as Vonage to connect with an IP PBX? I have found in researching this that these types of companies don't really offer a solution other than connecting via their router for every two trunks, which really doesn't work when you use T1s for long distance.
In the case of Vonage, your most practical solution may be to use a product such as OnDO PBX
You may also want to discuss this issue with Vonage users who have attempted to connect their Vonage service with an IP PBX. The best way to reach a large volume of Vonage users is by making a post on the independent Vonage Forum. The Forum receives more than 50,000 page views a day and is a great resource with plain talk and no marketing bull.
