[Asterisk-Users] Help, Ideas and Ready for use Solutions

[Miroslav Nachev]

   Dear Scott,

   The idea is to be used new SIP phones instead legacy phones. With
this the network cables (UTP/FTP-5) will be used instead one cable
network for the Computers and other cable network for the Phones.

If there is already an existing phone system in place, you could
easily migrate to an asterisk based solution if your internal phones
are analog.  The big question for you is not number of phone lines,
but peak utilization.  Here's what I have.

141 Analog Phone Lines
15 SIP IP Phones (Mix Cisco 7960 and Polycom IP500)
T-1 E&M For Long Distance
PRI For Local Calls with 200 DID Numbers.
Max concurrent calls 15-20 (30-40 active channels)

I serve all of this from a machine with the following config

Dual Xeon 2.4 Ghz
2 Gig Memory
3x36 Gig SCSI Drives in Hardware Raid 5 Configuration.
2xT400P 
6xAdtran TA750 Channel Banks with 6xQuadFXS cards in Loopstart Config.

This is more than enough for my call volume.  The CPU utilization is minimal. 

As you need more functionality at each phone location, you could switch to IP phones as needed.  



If you are starting from scratch, you will have a higher startup cost in equipment.

   Hi,

   I would like to ask you for advice how to solve the following case:
   I have a client (who happened to be my friend) and I have convinced
him that the IP PBX solution is much better than the conventional
telephone centrals (PBX). At the beginning he wanted to buy PBX
Panasonic, but at this moment he is waiting for my decision. Because
at the moment we are not so deeply familiar with these technologies to
be able to offer him all at once, we need your help. My client wants
to have 100 internal telephones, and between 10 (existing analog lines
to PSTN) and 30 (E1/PRI ISDN) external telephones.
   Is there any ready solution for this case we could use and how much
it will cost?

   Thank you in advance.


   Best Regards,
   Miroslav Nachev
