Missed calls log missing

It happens to some Cisco IP phones that missed calls log become empty. It is a weird situation and it may confuse the end users. You may see this behavior in ccm 7.x version. The problem won't go away even if you reset the firmware to default version and then upgrade to the latest version. The best solution is to remove the phone device and directory number from the data base. make a search that directory number does not exist in call manager. Then create the phone and assign the directory number to the phone.

reomote mobility voip phone set up for a group

Cisco Remote Mobility phone set up for a group of people:

By default we can add 4 cell phone numbers for remote destination in call manager. There are certain timers that we can adjust to get the preferred cell phone ring first.

The following timer settings will ring the preferred cell phone number first.

Preferred cell phone Number 1
Answer too soon timer : 2000
Answer too late timer : 19000
Delay Before Ringing timer: 0

Cell Phone 2

Answer too soon timer : 2000

Juniper SRS FW Redundancy

you must connect the fe-0/0/7 port to the fe-2/0/7 port to form the control link. For

SRX240 devices, connect the ge-0/0/1 port to the ge-5/0/1 port to form the control

link. For SRX650 devices, connect the ge-0/0/1 port to the ge-9/0/1 port to form the

control link. For a device from the SRX3000 line, the connection that serves as the

control link must be between the built-in control ports on each device. SRX5000 line

devices do not have built-in ports, so the control link for these gateways must be the

control ports on their Services Processing Cards (SPCs) with a slot numbering offset

of 6 for SRX5600 devices and 12 for SRX5800 devices.

FABRIC PORT CONNECTION

The fabric link connection for the SRX210 must be a pair of either Fast Ethernet or

Gigabit Ethernet interfaces and must be any pair of either Gigabit Ethernet or

10-Gigabit Ethernet interfaces on all other SRX Series devices. Figure 170 on page

912, Figure 171 on page 912, Figure 172 on page 912, Figure 173 on page 913 and Figure

174 on page 913 show pairs of SRX Series devices with the fabric links and control

links connected

Juniper NSM HA Setup

In HA deployment:
Copy the above 2 files to the primary and secondary server as shown above and ensure that files ownership are nsm.

Then instead of restarting GuiSvr & DevSvr service, perform the following:
Stop the HaSvr process of the stand-by server:
NSMStandby # /etc/init.d/haSvr stop
Restart the HaSvr process of the active server:
NSMActive # /etc/init.d/haSvr restart
Once the services on the primary server are all up and running, start the HaSvr on the stand-by server:
NSMStandby # /etc/init.d/haSvr sta

IDP Database update

Upon the installation of your NSM...before you can add you IDP appliance, you must update the attack database...this would mean.. your nsm server will query the juniper website where the idp attack database resides...

one of the requirements on updating the attack database is that your nsm server must have direct access to the internet...with proper dns configured.

Once this is addressed, just click on the NSM Tools > View/Update NSM Attack Database.

Juniper IDP

The unit can operate in either passive mode, or inline mode. Passive mode is just for sniffing the network, and it can block certain types of attacks by landing an RST packet within the TCP window. However, it cannot block non-TCP attacks, only log them. And it is possible that the blocking that is available in passive mode can happen too late, the malicious payload has already been sent by the time the blocking happens.

In inline mode, you have 3 options for installing it. You can use Layer-3, where the IDP gets an IP on each interface and you actually set up routes to it. In Bridge mode it will participate in spanning tree, and transparent mode, it just passes everything unmodified including spanning tree packets.

If you plan on putting the unit inline, Transparent mode is the preferred method. Especially if you have 2 units and are putting them in parallel between two switches as spanning tree will continue to operate as if the units were not even there.

When running in inline mode, you can group interfaces into Virtual Routers. These don't necessarily route, unless you're operating in layer-3 mode. But, the do tell the unit which interfaces are grouped together so you can pass traffic for particular network segments, and VR's will NOT pass traffic between each other. So if I had 8 interfaces, I could create 4 VR's with 2 interfaces each, and effectively put the unit inline on 4 totally separate network segments. Inline mode is the way to go if the unit will handle the throughput.

Set the unit up through the web interface on the unit to configure the modes you want to run in and any Virtual routers. Then install the NSM on your management console and add the device. When creating your policy, it's good practice to only put it in logging mode for at least a couple of weeks to see what kind of alerts you are getting and make sure you don't block legitimate traffic. Then go through and put in any exceptions you need and eventually put it into blocking mode.

Mobility - One number to reach

Intercom a type of phone line, combines the functionality of a traditional line and a speed dial. With an intercom line, a user can call the intercom line of another user, which auto-answers to one-way audio whisper. The recipient can then acknowledge the whispered call and initiate a two-way intercom call. Users can use an intercom line to dial any other intercom line in the intercom partition, or you can preconfigure the line to target an intercom line outside the intercom partition.
The following are the steps to create
1. Create intercom partition- Intercom partition is already created in Call Manager.

2. Intercom calling Search Space: Intercom CSS already in Call manager, we are using INTERCOM 10 for the configuration.

3. Create INTERCOM Translation Pattern:
Go to Call Routing > Intercom > Intercom Translation Pattern, Add New

Please add the directory number of the user who uses Intercom. The details of the fields are
Intercom Translation Pattern Enter the intercom translation pattern, including numbers and wildcards (do not use spaces), in the Intercom Translation Pattern field. For example, for the NANP, enter 9.@ for typical local access or 8XXX for a typical private network numbering plan. Valid characters include the uppercase characters A, B, C, and D and \+, which represents the international escape character +. If you leave this field blank, you must select a partition from the Partition drop-down list box.
Note Ensure that the intercom translation pattern, which uses the chosen intercom partition, route filter, and numbering plan combination, is unique.
Check the route pattern/hunt pilot, translation pattern, directory number, call park number, call pickup number, or meet-me number if you receive a message that indicates duplicate entries. Alternatively, check the route plan report if you receive a message that indicates duplicate entries.
