This can be caused by improper assignment of nodes to servers on Allstarlink.com.? For most of us, there should be a unique server with a unique binding address (4569, 4568, 4567, etc) for each node.? The binding address in iax.conf must match the binding address in the server.? The binding address must be port forwarded (UDP) in your router.
It is possible to have more than one node per server but I leave that to the experts:<)
Also consider asking your question on the arm-allstar list used to support the HamVOIP image.??
