How to setup and configure VOIP at home using Cisco 3660?

We are looking at getting some starter equipment to learn how to setup and configure VOIP at home. Currently we have a Cisco 3660, just two ethernet ports, an Cisco 2900XL switch and a Cisco 2600 router that is not in use right now. We also have a ASA 5505, that everything goes through for the internet. My question is what equipment do we need in order to setup a small working VOIP lab at home? We know we will need a VOIP phone or two, but what else would be needed with the setup we already have.

Tips:

  • Grab a couple 7960s and you can run CME on that router if you run older code (I think up until 12.4(15)T has CME built on the 2600XM). I'd recommend two routers, perhaps, so you can trunk between them.
  • DSPs are what converts analog or digital audio from a POTS (telephony) interface into an RTP packet. For the 2600, DSPs will be in the NM-2V or NM-HDV card.
  • For a 2600XM, if you wanted to connect an analog phone: NM-2V with VIC-2FXS
  • If you wanted to connect an FXS port to another router, the other side would have: NM-2V with VIC-2FXO.
  • If you wanted to simulate a PRI between two devices, each side would need: NM-HDV with VIC-1MFT-T1.

Unity Express 7- How do we restore or recover the voicemail system ?

We have a Unity Express system which has been configured and working fine since the installation. Voicemail number is 5000 and AA is 5001.Last week the voicemail system stopped working - nothing has been changed on the system it just stopped working. When we dial the 5000 number we get the voicemail system telling ' Voicemail system is unavailable try again later. To speak to an operator press 1" .We 've reset the NME-CME module, reloaded the router and still get the same message. AA is still working ok and we can see the calls coming into the NME-CME when we dial the 5000 and 50001 numbers?How do we restore or recover the voicemail system ?

Tips:

Have you been using a temporary license ? Check "show voicemail mailbox", and "show license". You can readily obtain a permanent license from the licensing portal.Please click here for licensing .

If the CFNA target of the CBG is AA how do you plan for calls to reach the GDM VM box?

We have a UC560 running 8.0.2 and we are using CCA 2.2.4 to configure it.We have a few questions regarding Call Blast Groups (CBG) and General Delivery Mailboxes (GDM).

1. When we create a GDM for a CBG there doesn't appear to be any MWI option. Is this correct, or are we missing something?
2. We would like to create CBG's that have CFNA go to the Auto Attendant, but we would also like a GDM associated with the extension of the CBG. It appears that these are mutually exculsive. Is this correct.

3. We would like to create CBG's that have CFNA to the Auto Attendant, but also create GDM's using the extensions of the CBG's with MWI (along with the MWI for the user) on the Primary Extensions of the users which are members of the CBG. This is for the AA after-hours option. We want calls to go to the GDM VM box so when members of the CBG come in the next morning, it is simply first-come-first-servered for access to the messages in the GDM. Is this possible?

Due to real-estate issues on the phones, we would prefer to not create "dummy" user shared-line extensions on the phones.

Tips:

1. The only way the phones would be able to receive MWI for the GDM vm box is if there is a line appearance on the phones with the GDM pilot number. What some people do is create an ephoen-dn with the GDM pilot number and create a monitor line to that ephone-dn. However, this might not work in your case b/c if the ephone-dn has the same extension as the hunt pilot of the blast group it may conflict when someone tries to dial the pilot number.

2. That's correct. From a configuration stand point CCA would create a GDM when the CFNA target is VM. If it's set to AA it would not create a CUE GDM VM box.

3. If the CFNA target of the CBG is AA how do you plan for calls to reach the GDM VM box?

When there is a VM in the GDM CUE sends a MWI notification for the GDM extension or pilot. CUE does not send a separate MWI notification to each extension apart of the group. The only way that each phone would be able to have their MWI lit or an envelop icon displayed on their phone is if there is a line appearance of the GDM extension on each phone that you want to receive the notification for.

IP Phone 6921: How can we downgrade from 9-0-3-0 to 8-5-3-0?


We have some IP Phones 6921 with firmware 9-0-3-0 and we would like to downgrade their firmware to 8-5-3-0. Although the TFTP server is correctly loaded with the 8-5-3-0 firmware files, the 6921 doesn't downgrade to it. If it isn't possible, is there a way to completely delete the firmware and download a new one on the 6921, similarly to what explained in Cisco's web page for 7906s and 7911s?

Once you load an unsigned image, the next upgrade or downgrade has to be to a SIGNED Firmware image. For example

You have one 6921 on 9.0.2 unsigned FW, I would recommend you to upgrade all your new 6921s to 9.0.3(unsigned) and then once every 6921 is on unsigned **image, you can go ahead an load 9.0.3 *signed *and upgrade all of them together. Please note that a new 6921 runs 8.5.4 which needs to be upgraded to an *unsigned *image (9.0.2 or 9.0.3) first.
You can download the appropriate locale files (cisco login required) from here.

Here are some pointers on the locale install.

Please note that Cisco Unified Communications Locale Installer *MUST* be installed on every Cisco Unified Communications Manager server in a cluster, starting with the publisher. After installation has completed,it is essential to reboot the platform in order for all user and network locale changes to become fully activated.(Please click here access the install locale instructions). If the previous download doesn't work, then try cm-locale-fr_FR- FR locale) which has the FR locale for allthe phones for CUCM 7.1.5. NOTE: * The full Cisco Unified Communications Locale Installer for Cisco Unified Communications Manager must beinstalled prior to installation of Phone Only locale.*(Please click here for the CUCM Locale Installer ). CUCM Locale installer file names start with *cm-locale*. and phone locale installer file namesstarts with *po-locale*.

As per the information given by you, You have a locale issue with the 6921s. So try the po-locale first. If that doesn't work then try the cm-locale upgrade. Please be aware that there is bug CSCtf40828 . Please click here for the bug details (Cisco login required).

How can we do a time based forward of calls in CUCM6.1 ?

We want to forward all the calls coming on one phone to a particular number only in the office hours and during night it should land on the same IP phone. Scenario is we have a call centre and during the day calls are routed to somewhere else and during the night , calls come to our place but the direct line is terminated on our site. So today we are doing it manually everytime , we want to do this automatically, from say 9am-5pm it should go to other site and from 5pm to9am it should come at our site.

I'm not sure if this can achieve what you want, but you can take a look on something called Time-of-Day routing." Time-of-Day routing routes calls to different locations based on the time of day when a call is made. For example, during business hours, calls can route to an office, and after hours, calls can go directly to a voice-messaging system or to a home number. " Please click here for the document .

Please click here for the Unified Communications Manager 6.x: Time-Of-Day Routing Configuration Example. You may also find this recent thread very helpful.
