Hi, Does anybody has experience with high capacity PSTN voicemail and asterisk, running more then 5k mailboxes for PSTN users ? How many mailboxes can I serve with 4xE1 card if we assume that we have enough harddrive capacity. What would be server requirements. Would the CPU load be the same when storing voicemails in gsm format as compresing to gsm for ip calls ? Any hints would be greatly appreciated regards m.

Forget using ATA hard drives. You'll want to be shopping for a storage solution that has as little impact on CPU resources as possible. -- No virus found in this outgoing message.

There was some discussion about this on the list a few months ago. It seems like there was an issue with inode directory space for that many files or not enough descriptors. I can't recall exactly, but you will want to do more homework to make sure the filesystem can handle the quantity of files and directories. -Nate -----Original Message----- From: izo [mailto:marcin.izo@gmail.com] Sent: Thursday, February 24, 2005 7:12 AM To: asterisk-users@lists.digium.com Subject: [Asterisk-Users] High capacity voicemail Hi, Does anybody has experience with high capacity PSTN voicemail and asterisk, running more then 5k mailboxes for PSTN users ?

Marcin, This depends enormously on the type of users. For 5000 users, I would normally recommend IBM's Unified Messaging product. For business users on that, I normally recommend at least one E1 per 2000 users as a starting point. For residential users, at least one E1 per 5000 users. IBM-UM is voicemail with web and email interfaces (which reduces traffic) and a lot of follow-me and operator services (which increases traffic if you can't do release link transfers, and reduces it if you can). Asterisk would be similar. If you can do release link transfers, then you can get more users per trunk; in some scenarios up to double the number. The above figures assume you can. The above figures are just a starting point; there is a good chance that your users are not typical. For example, in some countries in Asia, you can support many more business users - if callers hear a voicemail greeting, they usually hang up immediately, and call the person's mobile phone. You really need to do a pilot with a subset of users to gauge how much they use the system, and what features they use. For 5000 users, I would also consider some form of redundancy and automatic failover. 5000 angry users is not a pleasant sight! My company, Integrics Ltd, does consulting and installations of both Asterisk and IBM-UM. If you'd like help planning and installing such systems, drop me an email or give me a call.
