I am preparing to take the 640-802 CCNA exam and I am reading the Todd Lamelle Sybex book. I notices in most chapters the "Cisco Router and Security Device Manager" GUI interface is included. Does the exam really cover this application?

We are moving away from a front end Nortel PBX with a valcom paging system to full Call Manager. There are four zones for four different floors. We have experience tying out a paging system with one zone, but not with four. Would we just duplicate the four zone using a four port fxo card, one...

Thank you this is really helpful.

What about using a few SIP trunks instead of going through a local carrier? Do you have any experience with this kind of connection? Thank you for your feedback.

The goal is to provide IPT to the office via our centralized build in the most cost effective way possible. We currently only use the MPLS WAN for call set up, tear down and voicemail. With a 15 person office I could probably set them up with 5 or 6 pots lines and tie those out to a few fxo...

We have a central Call Manager 5.1 and Unity 4.2, they would be set up as our other remote offices with a gateway router with connection via an MPLS link. I am thinking to not at least have some pots lines for SRST in case of a WAN failure would be kind of crazy. It will be a 15 person office...

We have a small office in London that is asking if they can be included in our NY based centralized VOIP offering. They are interested in keeping their current phone number, and are wondering if they can have that and be set up with an MPLS link to our office, without subscribing to local PSTN...

Thank you for the link. I actually tried to use the DSP Calculator and I found it a bit confusion, I am setting up a 3825 router with two dual port vwics and one wic for an MPLS connection. I am also using a four port fxo card. We have about 340 people we will be moving to voip and I want to...

Soes anyone know a basic calculation for figuring out how many DSP's are necessary on a gateway? Please share if you do. Thanks. Rgds, TJaw14

We are migrating an office with a key system to a 2851 SRST router. The current system provides four fax lines that are actually digital lines that the system converts to analog signal for the fax lines. I believe I can achieve the same conversion using an FXS card but I am not sure of how the...

I am in the process of matching up the info from bell canada with the router config. I am concerned about the Norstar but I'm not clear on whether or not I should power it down. I think I will just move the RJ45 connection from the norstar to the router. If we run into a problem I will...

Hi trying2help, I will most likely reach out to the carrier to let them know in advance so that I have a sound fall back plan. Thanks for the input. Rgds, Tjaw

Hi Sam, So if the worst should happen and I need to reconnect the old norstar system it would be as simple as reconnecting the rj45 for the PRI and powering the norstar back up, correct?

We have just completed a migration from Unity 4.0(5) running on a win 2000 platform to a Unity 4.2 running on a win 2003 platform. We tried to use exmerge to bring the old messages from the 2000 server using exmerge 2000 to the new server using the native exmerge 2003 ini file on the new...

Hi all, We are planning a migration in one of our offices from a Norstar to a cisco SRST remote site that will be tied to our office via a MPLS circuit. We will be continuing to route calls over the PSTN. We are planning on moving the RJ45 connection that is currently plugged into the Norstar...

Many thanks Packet7. Rgds, Tjaw

Hoping someone here has had some experience re-provisioning a PIMG box when performing a Unity voicemail upgrade. If so, is there a config on the box? Do you need to restore to default and start from scratch to make the new Unity server see the new IP address. I am asking this because we have...

Hi Iwontremember, No worries, I remembered you!!! Thank you so much, this is a huge help! Rgds, Tjaw14

Hi Iwontremember, Thank you. I was wondering about whether or not the unity would get hung up with all the users listening to the voicemail message at the same time. If you can post the instructions that would be great! Thank you again. Rgds, Vicky

Hello all, Does anyone know if you can leave a message for all of your voicemail subscibers using a unity public distribution list. I want to be able to create a voicemail message and send it out to all of the unity voicmail subscibers at once. Is this possible? Any feedback is greatly...
