  • Back up from VM to UM for call handlers - ( 03-22-2004 )
  • Unified Communications Infrastructure
  • Unity 4.0.3. I do have 2 Unity servers. 1 with VM only and the other one UM. I do have over 100 call handler programmed in VM corresponding to a site. In case that this Unity server fails, I would like to have those call handler transfer to the UM server, but not the regular forward of the subscribers (licensing issue). So I did tests a CTI route point,(forw all to VM) but unfortunatly, it doesn't take the forward no answer when VM server is down. It takes the forw no answer of the port itself. Did try with pilot point and hunt group and got the same results. Does anyone have any idea on how to do that?

  • 4235 IDM and VMS hang and won't connect - ( 03-18-2004 )
  • Other Security Subjects
  • I've got a 4235 that we are managing and IDM nor VMS will connect to it for management purposes. We have opened a TAC case but they haven't figured it out yet so I figured I'd see if anyone out here has some ideas. We already downgraded and upgraded and the problem persists. This is the second device we have had at this location and problems were similar. If I try to connect with IDM, I get the certificate banner but no IDM display (just the spinning globe) so I know my access-lists and routing is set up okay. I'm including a snoop session for the IDM connection and you will see the three way handshake and some communication and then the IDS (10.42.46.83) just seems to keep pushing an ack until the timeout and then it sends a FIN. I've tried this connection from several IE clients on different machines with the same results.

  • Voice over IP
  • Hi,i have set up an IAD2400 to use VoATM as outlined in the book:"VOAAL2 Profile 9 configuration" and the lines do come up and work as advertised, however; after a few minutes of being idle, we loose connectiviry and the only way of getting it back is to reset the voice ports. The CO voice gateway specifies the following: aal2 Bles mode, Cas-gr303 signaling,CAS refresh every 5 seconds, Idle CAS refreshing enabled and Combined use timer of 20 ms.I have looked but so far I can't find the setting fo enable the idle cas refresh rate that i suspect is the problem.please help and thank you in advance

  • I need some help / Advice We have a remote office that is connected to the outside world via a Frame Relay connection through a Cisco 2600 router which is also doing all NAT duties. We have a sonicwall at the remote office and the head office sites and have created a SonicWall to SonicWall VPN.

  • Ciscosecure ACS upgrade problem. - ( 03-14-2004 )
  • Network Access Control
  • Hi,My intention is to upgrade our old ACS v2.4.1 NT ACS Server to a new v3.2.1 Win2000 ACS server. As described on this forum, I am following the process 2.4.1 to 2.4.3 to 2.6.4 to 3.0.2 on the old NT box and then replicate to 3.0.2 on the new Win 2000 box. I managed to upgrade the old NT box to 2.6.4 without issues. However, I have a problem going from 2.6.4 to 3.0.2. During the installation I get this error..."ODBC Microsoft Access 97 driver login failed" - "Unrecognized database format "C:\Program Files\CiscoSecure ACS v3.0\CSAuth\VarsDB.mdb."Any ideas why this is happening? The first two steps 2.4.1 to 2.4.3 to 2.6.4 upgraded fine.Many thanks,Steve.

  • Network Access Control
  • Is it possible to have ACS do the following: - RADIUS Authentication for WLAN users against Active Directory - RADIUS Authentication for for VPN users against SecureID Server...such that user jdoe will use either of the above methods of authentication depending on his method of access? Basically, can ACS do different authentication methods for the same user-ID depending on the authenticating device?

  • OSPF MIB - Multiple OSPF processes - How to get the OSPF TE data? - ( 03-11-2004 )
  • MPLS
  • We have three ospf processes on the router: router ospf 1 ... Core ospf that is supporting RSVP & MPLS-TE. router ospf 2 vrf ipvpn-A ... PE-CE ospf to customer A. router ospf 3 vrf ipvpn-B ... PE-CE ospf to customer B.Using CLI, when we ask for ospf information, e.g., show ip ospf databaseit is dumping in arbitrary order: OSPF Router ID (10.9.3.1) (Process ID 2) ..... OSPF Router ID (10.8.3.1) (Process ID 3) ... OSPF Router ID (20.1.3.1) (Process ID 1) ...process ID 1 is the one we need for core bandwidths and MPLS info. However, using OSPF mib, we see only the data for the first OSPF process, which is on a VRF and doesn't have MPLS-TE data. How can we get the OSPF TE data from the MIB for a particular ospf process?

Also, if you can upgrade to newer IOS's without smartnet, what would be the reason to have the smartnet coverage on them?

  • DHCP and DNS to help categorize workstations - ( 03-08-2004 )
  • Server Networking
  • We use DHCP and dynamic DNS updates. Our apps folks want to be able to identify groups of clients by apps they use. For example, a workstation used at BED1 would have the DNS name of bed1.cicu.hs.uab.edu. The app that CICU's use will limit access to the desktops that have *.cicu.hs.uab.edu names. There will be a number larger than one of these categories on most floors.

  • PGM Router Assist - Option bug? - ( 03-03-2004 )
  • Other Network Architecture Subjects
  • Hi,We'll appreciate any insight on this issue.When implementing a PGM client server application we encountered a problem with the way our Cisco router (model 2651) interprets the Option field in the PGM header. According to the PGM standard (RFC3208) the option field is defined as follows (section 8 page 32):[ Options:This field encodes binary indications of the presence and significance of any options. It also directly encodes some options. bit 0 set => One or more Option Extensions are present bit 1 set => One or more Options are network-significant.... Bits are numbered here from left (0 = MSB) to right (7 = LSB).]To the best of our understanding it follows that to indicate an option is present the value of the option field in the PGM header should be 0x80 and if a network significant option is included the value should be 0xC0.Our cisco router however expects the option field to be 0x01 for options presents and 0x03 for network significant. That is the router expects the bits to be in revers order.Obviously when encoding packets with the option field as defined in the RFC standard the router does not process the options. The main problem is that the router does not process NAK lists and hence prevents the receivers from getting repair data. To solve the problem we had to change the bit order in the option field.
