Hi all
I have an SV9100 that has 6 SIP channels, incoming calls are no issue, outbound works well MOST of the time. However accasionally when pressing a trunk key you receive busy tone, which can last for up to 2 or 3 minutes before being able to again make an outgoing call. I believe port forwarding on the router is correct otherwise NO outbound would be possible I assume. Never any issue with the inbound calls. any insights would be appreciated.
