No. Though, I find the AudioCodes GUI and documentation to be perplexing, and might simply be overlooking something. You can however specify a list of IP addresses that the gateway should accept INVITEs from (up to 50.) So the AudioCodes "Secure SIP Calls" feature is compatible with direct gateway dialing. But they're painful to use together, since you'd need to enter all the phone IP addresses into the little "Accepted IP Addresses" edit box in sipXconfig. Actually, sipXconfig currently limits the length of the string. To get 50 IP addresses in there you'd need to use the AudioCodes Web GUI. Using these two features together is also a bit risky. If the phones use DHCP, or otherwise change IP addresses then they may suddenly be unable to dial emergency numbers. These are more good reasons to avoid using direct gateway dialing from the phones. The latest plan is to turn off automatic direct gateway dialing. This is covered under XCF-3581, though it isn't currently scheduled. Damian, can you confirm that XCF-3581 is indeed planned for 4.0? -Paul [email protected] _______________________________________________ sipx-dev mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-dev Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-dev
