RE: [Asterisk-Users] Newbie Question-Looking for Feedback
Greetings all. I am new to the Asterisk world! Found it very impressive so far! In relation to the below. I have worked with Alcatel PBX's for the last 3 years. Alcatel OxE supports SIP and H323 as well. As far as SIP goes I have also found the Xlite to be good for soft phones. I am using one now. Check out www.xten.com Xlite is free and easy to use. I also have been given a Pingtel SIP to play with. http://www.pingtel.com/ As far as H323 terminals go I have not played with all that many, however the simple Microsoft netmeeting works for testing purpose anyway. Now a question to all you experts out there, and this may seem VERY stupid, but I have configured the sip phone and have it logged in and can dial 500 to get to the sample messages etc. However i cannot work out how to give the sip termainal a number that can be dialled. I would assume that it needs to be in the dialplan, so I have added it in via the extensions.conf file, however I am sure that I have stuffed the config somewhere. Can someone please point me in the right direction. Would be much appreciated. Also, do i need hardware to make a SIP to SIP call... eg. Compressors etc. Cheers Chris -Original Message- From: WipeOut [mailto:[EMAIL PROTECTED] Sent: Thursday, 8 January 2004 8:32 AM To: [EMAIL PROTECTED] Subject: Re: [Asterisk-Users] Newbie Question-Looking for Feedback M.

Back in December there was a thread or remark about a Digium quad FXO card. I would like to know when Digium will start marketing this... M.

RE: [Asterisk-Users] Newbie Question-Looking for Feedback
Goal Provide phone service using the Asterisk system running on standard PC equipment for four concurrent phone conversations. Calls will come into the Asterisk system where they will be answered via VoIP. VoIP will be provided via the internal 100mbit/s ethernet network and optionally from the internet via a T1 line providing 1.5mbit/s. Setup = We're a small business inducted to the Asterisk world in an attempt to provide a real phone system to customers and our remote employees. The #1 attraction to Asterisk is it's low cost, feature set and the fact that it's opensource (linux). In a previous email, I asked for a bit of direction in what type of configurations would be best suited for our environment. I've taken as much feedback and suggestions and formulated three different configurations that seem to solve the goal. Each of the configurations seem to advantages and disadvantages. Questions = The number one question for each configuration is Will this work? and Does anyone else run this configuration in their environment? (Configuration Diagrams are below the Questions) Configuration #1 - Can our telecom company provide two ISDN BRI lines. Each ISDN line providing 2 channels of 64kbit/s? - What manufacturer/model of ISDN adaptor is best supported by Asterisk? Disadvantage: Seems to be a rare configuration based on what seems to be antiquated technology. Advantage: Cost. I estimate the two ISDN BRI cards to run $100/each with minimal investment in the telecom provisioning. Configuration #2 - Are there cheaper, less extensive channel banks which might be more cost effective for our limited scalability needs? Disadvantage: Cost. The channel bank runs about $1700-$2000 retail with the 8-port FXO service card. Advantage:Future Scalability. However, I don't perceive servicing additional phone lines and if we did, it would most likely be done by pulling some data channels off one of the existing T1s and sending it directly to the Digium T100P. Configuration #3 Advantage:Cheap Disadvantage: Suspected Reliability. In reading posts from other users of these cards, there appears to be a serious chance of IRQ conflicts and echo problems using this many single port FXO devices in a single machine. Digium does not currently produce a =2 port FXO version of the card. CONFIGURATION Diagrams == 1. Switch the four POTS lines to 2 ISDN BRI lines. Install 2 cards which are 2-Port ISDN BRI Adaptors. ISDN BRI ISDN BRI Line #1 Line #2 || ++---+ | v AVM or Eicon 2 Port Card 2. Bundle the four POTS lines with a channel bank (creating a T1 with 4 channels used) Using a T1 cross-over, connect the channel bank to the Digium T100P POTS 4-Lines | | | | +-+++-+ | v Carrier Access ADit 600 | v Digium T100P 3. Take each of the four POTS lines and simply plug them into four distinct Digium Wildcard X100P adators. Downside is that this isn't a recommended procedure as there might be IRQ conflicts and echo induced by the multiple adaptors. POTS-1 POTS-2 POTS-3 POTS-4 | | | | v v v v X100P X100P X100P X100P | | | | +---+---+---+---+ | v TDM400P 4 Port (to make analog lines from *PBX) Hard Phones: Snom 200, Grandstream ($70), Cisco ($$) Soft Phones: X-Lite, X-Pro -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of WipeOut Sent: Wednesday, January 07, 2004 1:32 PM To: [EMAIL PROTECTED] Subject: Re: [Asterisk-Users] Newbie Question-Looking for Feedback M.
