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? _____________________________ Jan Fricke (B.Sc.) *IANT - APPLIED NGN-TECHNOLOGIES **Turn-Key VoIP/UC Solutions and More... *Fon: +49 (5331) 6794 0 Fax: +49 (5331) 6794 499 Mail: [email protected] Web: www.iant.de <http://www.iant.de/en/startseite> IANT is eZuce <http://www.ezuce.com/> Elite Partner for EMEA IANT is Member of GROUPLINK <http://www.grouplink.de/>
