Cisco hosted Call Manager and Unity Solutions

We have a site with about 75 users. It is running an older version of Cisco Call manager (4.1) and Unity. The hard drive on the Unity server died and because the product is end of life, i can't get support on it. So i'm dealing with the nightmare of everyone being without voicemail.

I want to push these services on the cloud and want to know if anyone can recommend some service providers who provide hosted Cisco solutions. I guess it could also be non Cisco since I believe the 7940 and 7960 phones are all SIP compatible.

IMO you might be better off by migrating to a CUCMBE CUCM Business edition (CUCM and Unity Connection in one Linux server), or Call Manager Express, because you have already invested into the CUCM and Unity licences. A hosted solution may become more expensive in the long term. You only have 75 users. A Call Manager Express on a 2921 ISR router with ISM-300 Unity express will be sufficient. In my opinion a CUCM+Unity cluster is an overkill for only 75 users.

We are on trying a hosted solution on a trial basis with M5net. The implementation of this has been pretty easy. We are actually going live today on it. I believe this is going to be very cost effective for us and we will be nearly eliminating the managment headache for and on site Cisco equipment.

You will not have the luxury of being able to do everything you like whenever you wanted, but on the ohtner hand you do not need to employ a qualified/competent ip telephony system engineer, and worry about backups etc either. When you think that a single CUCM server can handle about 2500-7500 handsets, obviously it is targeted for medium to large organizations who can afford a competent IP teephony enabled systems engineer. Especially with the version you have, you also need to take care of the windows servers, and as the devices get older, best practices for backups etc become more important. A single site with just dial tone and voice messaging for 75 users definitely does not justify maintaining a CUCM cluster.

I hope the hosted solution works well for you.

So far so good with the hosted solution. Hosted solutions generally want a point to point T1 installed to insure good voice quality. However, after doing some tweaks to prioritze the VoIP traffic, I'm not not even sure the dedicated circuit will be necessary. The voice quality is very good after the tweaks. At this company anyways, people are waaaay more upset if there is a problem with being able to browse the internet then surf then using the phones. Plus these days, who doesn't have a cell phone?

Kind of glad to be off the Call Manager/Unity upgrade cycle, with all the Smartnet and everything else it is just too expensive.
