Forget to mention another important thing. Many people are using a betamax brand to call thru sip. Betamax and pbxes have always been tricky.
Since you share your ip with many many other users this means that you can't use the betamax free days. Betamax limits this to 300 minutes per 7 days per ip. You can imagine if you have 500 users these 300 minutes are used fast.
The next problem is that since last week betamax has blocked most of pbxes ip addresses, meaning no one is able to use a betamax clone to make calls.
When looking at the errorlog you are requested to use there wholesalebrand
Voice Trading. Wholesale VoIP solutions instead.
The only reply pbxes.com give on this topic is that they think you should just use another provider. This is another example on how arrogant the operator of this service is.
They have never really tried to solve the problem between betamax brands and pbxes.
Yes another reason to stay away from pbxes.
