I programmed a sip line on an IP500 V1 running realease 6.0.18. After rebooting, I get the confirmation from the sip provider and able to make a call to the pbx. When I try to make another call and any call after, it rings busy.
The monitor trace shows that the pbx is trying to authenticate with the sip provider but never receives confirmation from the provider so the pbx does not know where to route the call and returns a busy signal while the sip provider sees confimation on their side and says everything looks good and is therefore blaming it on my end. I had to reboot again to be able to make another call and the problem reoccurs thereafter. Has anyone experienced this with 6.0 and is there a possible solution? The sip provider is not supported by Avaya TSO.
