If you're already using POTS phones and want the flexibility of SIP you may just want to get SIP adapters that you can continue to use your POTS phones with. I recommend the Sipura SPA-2000 dual analog adapter(www.sipura.com). You can get them for about $92(if you get more than 10 in one order) and each one handles two analog phones. They have a lot of features and great support. We are currently using them on over 80 analog phones across 3 Asterisk servers and they work great.
A cheaper option might be using channel banks for your POTS phones but that may only be cheaper if you buy a used one, and then you wouldn't have the flexibility of using SIP adapters, and you would probably need to get a quad T1 card if you were planning on only getting a single T1 card, which would make it much more expensive overall. Hope this helps. Good luck MATT--- -----Original Message----- From: Tim Guy [mailto:[EMAIL PROTECTED] Sent: Friday, June 18, 2004 11:37 AM To: [EMAIL PROTECTED] Subject: [Asterisk-Users] UK install Well I'm slowly learning my way around asterisk although as yet I haven't had the chance to actually hook the system up to an ISDN line. I am going to migrate from an Argent Office setup. My only problem is keeping costs down on the phones. The Argent system is running about 30 POTS phones. Can someone suggest the cheapest option? Should I get some kind of large scale FXS box or would the cost of doing that on a large scale work out the same as getting cheap SIP phones? I have a large number of POTS phones with headsets so I would have to take that into account if I replaced the phones with SIP's In an ideal world Id like to convert a number of POTS to soft phones but as always its persuading the users that they can operate in the same way. Our Telco is NTL offering us an ISDN 30 style package. I assume this is a E100P card requirement? Any suggestions for good UK reseller or shall I get it direct from Digium? Anyhow, as I say I'm getting more functionality out of Asterisk than I ever did with (personally thinking) a very confusing Argent setup. I just hope that I can make it financially viable to do the install Cheers Tim _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
