Hi all, I was just wondering if someone could help me with info on VOIP Gateways. We are planning to do an * install in an apartment building, this building is going to require somewhere in the vacinity of 20 E1 lines (each with 30 voice channels). Short of buying 20 Servers with Digium cards, what are my options in having the E1 lines terminate on some other hardware and then having the calls passed through to Asterisk to perform the PBX type functionality ? I have heard that using some form of VOIP gateway should help, but I really have no idea how this works. Any help would be appreciated. Cheers, Callum
Wait until the new card of Digium go out, withit you only will need 1 server more powerful. regards. ----- Original Message ----- From: "Callum McGillivray" <callummc@ains.net.au> To: <asterisk-users@lists.digium.com> Sent: Tuesday, April 26, 2005 9:29 AM Subject: [Asterisk-Users] VOIP Gateways & Asterisk> Hi all, > > I was just wondering if someone could help me with info on VOIP Gateways. > > We are planning to do an * install in an apartment building, this > building is going to require somewhere in the vacinity of 20 E1 lines > (each with 30 voice channels). > > Short of buying 20 Servers with Digium cards, what are my options in > having the E1 lines terminate on some other hardware and then having the > calls passed through to Asterisk to perform the PBX type functionality ? > > I have heard that using some form of VOIP gateway should help, but I > really have no idea how this works. > > Any help would be appreciated. > > Cheers, > > Callum > > > _______________________________________________ > Asterisk-Users mailing list > Asterisk-Users@lists.digium.com > http://lists.digium.com/mailman/listinfo/asterisk-users > To UNSUBSCRIBE or update options visit: > http://lists.digium.com/mailman/listinfo/asterisk-users
We do some least cost routing and pass calls to a Cisco AS5300 and are looking at also using a Lucent TNT. It's just a matter of setting up the dial plan in extensions.conf The cisco is using h323 and if the client does SIP the protocol conversion is done on the * box, otherwise it is basicaly just a hand off.

You might look into the Lucent TNT's, they do SIP/MGCP (with the Hash codes, os 10.1.xx+), and also terminate modem calls. They are cheap (check ebay, www.qualitek.net) and their are loads of them out there. One TNT will handle your requirements easily, their is an example on the wiki on how to use a TNT with asterisk, and it works properly. I used Asterisk to talk to them via SIP, didn't try mgcp but it should work fine.

You could just buy 5 servers with the 4 port E1 card. That might be cheaper.

As this is an apartment building, won't the tennants be looking for PSTN dial-tone, rather than local (PBX) dial-tone? Assuming that there is something missing here... You could treat this as a "hospitality" (hotel) type environment, but would certainly have to allow for a lower station:trunk ratio. Still, the thing to do would be to deploy channel banks (Adtran, Adit, etc.) that would be aggregated into the number of E1 ports on your * box required to handle the projected traffic. In other words, you will not encounter a condition where every station will be in use at the same time, so you don't need that many DS0's (channels, if you will) at the PBX. -- No virus found in this outgoing message.
