-----Original Message----- From: Mailing list for discussion of Firewall-1 [mailto:[EMAIL PROTECTED] On Behalf Of Miguel Hernandez y Lopez Sent: Monday, November 03, 2008 7:52 AM To: [email protected] Subject: [FW-1] VoIP - Calls thru Checkpoint NGX R60 and Avaya IP Office 500 Howdy, i´ve Checkpoint NGX R60_HFA06, the main problem is that VoIP calls from Avaya IP Office 500 don´t work, only works in one direction. In the Cisco switches we´ve vlans assigned to each subnet, each subnet are in both Firewall with an ip address of each subnet and vlan. Each IP Phone (10.2.24.57 and 58) comunicate to the CallManager, and the Call Manager has 2 intefaces (10.2.0.28 and 36) and the FileServer (10.2.8.14) to download the correct .bin, the calls between IP Phones work fine. Now, when we try to call from an IP Phone (10.2.24.57 and 58) to a extension in the IP Office Server (192.168.5.10) the call works fine, i see all the traffic pass thru the Firewall... but when a try to call back from the extension in the IP Server to an IP Phone the call die after dial the number, it sound busy tone. In the Firewall i only see accept H323 packets to the Call Manager and no other kind of traffic. I do a fw monitor zdebug and don´t see any drop packets from/to Ip Server. We do several test, putting the service H323 in advanced setting to none, h323 and h323_any.. with no success. At this point, i don´t no know where it can be the problem. do you have any suggestion?
