Hi,

I since a few days there is a problem with an openUC 4.4 system. Suddenly
no outgoing calls through the ISDN gateway (patton sn4960) are possible
until the proxy service or gateway is restarted.

I’ve captured sip traffic on the openUC and it shows that there were
incoming calls (isdn to voip). The gateway selects the TCP source-port  for
the Invites dynamically. In this case it’s 16086. openUC sends answers to
the Invite to this port. But I’d expect that outbound Invites (call from
voip to isdn) will use the port that is configured in openUC (unmanaged
gateway TCP port 5060). Instead it sends also Invites for new calls to
16086. The gateway only allows messages for the original call on this
dynamic port and answers 481.



Is this something known? Any suggestion how to solve this?
