SIP VoIP Trunking on BCM SIP VoIP Trunking on BCM seka (IS/IT--Management) (OP) 3 Aug 04 17:39 We're trying to get a BCM to connect to an external (non-BCM) SIP Proxy to terminate calls.1) Does the BCM support authentication by username, password? We can't seem to find it.2) Where do you enter the destination sip proxy/outbound proxy?Any help appreciated!S RE: SIP VoIP Trunking on BCM txrattler (Vendor) 4 Aug 04 10:21 SIP is only supported on BCM Succession 3.5. If you have a 3.5 Box then the info you are seeking are in the docs.ghostrider42us RE: SIP VoIP Trunking on BCM seka (IS/IT--Management) (OP) 5 Aug 04 02:14 I'm not sure I understand the docs, but I think the docs say that a BCM can only talk to another BCM using SIP. Is that correct? There appears to be no way to get it to register to a SIP proxy.Can it register to a gatekeeper using H.323? RE: SIP VoIP Trunking on BCM aragon (Instructor) 19 Aug 04 15:14 The BCM talks to other BCM's via IP Trunk keycodes.You may choose the signalling methods either H.323 or SIP.Standard trunks supporting MCDN are H.323SIP is less functional due to early release of code.BCM supports 3 methods of H.323 resolution:DirectGatekeeper ResolvedGatekeeper RoutedOnly supported gatekeeper that comes to mind right now is the RadVision H.323 stack. RE: SIP VoIP Trunking on BCM aragon (Instructor) 20 Aug 04 09:57 Refer to Using Radvision ECS 3.2 GK as the gatekeeper and Using CSE 1000 as a gatekeeper for specific information about configuring the gatekeeper for H.323 trunks.Network note: If your private network contains a Meridian 1-IPT, you cannot use Radvision for a gatekeeper.SIP trunks communicate between Business Communications Managers. The addressing for the remote destination is described in Setting up SIP trunk subdomain names.
