All, when it comes to VOIP, I was born yesterday (but I staid up all night). I was about to buy a Digium TDM404E with 4 FXO (Red) Modules and eight Aastra 6755i phones when it occurred to me I probably should ask the FreeSWITCH community if what I'm about to do is sane :] 8 endpoints (planned to be aastra 6755i) 6 people using phones (four concurrent PSTN lines busy at peak usage) (55 to 60 long distance calls at a current cost of $55 to $70/mo) I hope to create a VOIP hybrid (at first) where just the long distance calls are done via SIP. Later, I would disconnect PSTN2 and PSTN3 and use the SIP DID as the roll over group/hunt group once I have the system stabilized. ---------------------------------------------------------------------------- Inbound Calls ---------------------------------------------------------------------------- PSTN1->TDM404E| PSTN2->TDM404E|->FreeSWITCH->local ethernet network->(aastra 6755i endpoints) PSTN3->TDM404E| PSTN4->TDM404E| {will later disconnect PSTN2 and PSTN3 and use SIP DID as roll over group -and hunt for outgoing} ---------------------------------------------------------------------------- ---------------------------------------------------------------------------- Outbound Calls ---------------------------------------------------------------------------- SIP service (one DID)<-FreeSWITCH<-local ethernet network<-(long distance calls via aastra 6755i) PSTN2->TDM404E|<-FreeSWITCH<-local ethernet network<-(local calls via aastra 6755i) PSTN3->TDM404E| PSTN4->TDM404E| ---------------------------------------------------------------------------- ---------------------------------------------------------------------------- Ethernet Configuration ---------------------------------------------------------------------------- | -TDM404E->PSTN -DSL Modem NAT---3com Ethernet Switch---FreeSWITCH| | |_aastra 6755i--Computer (this represents eight endpoints/PCs) ---------------------------------------------------------------------------- ---------------------------------------------------------------------------- FreeSWITCH Server ---------------------------------------------------------------------------- Dell 1400sc Service Tag: JRRXJ01 **************** Hardware **************** BIOS ver A03 CPUs Two 1000MHz, fsb 133 Mhz, L2 256kb RAM 512MB ECC Video ATI Rage XL FDD CDROM Tape Drive (Archive Python 06408-xxx) Raid Controller: American Megatrends Perc2/D2 (Now LSI) bois v1p00, firmware ver 1.01 DRAM 128MB 15 scsi ids on each channel Harddisk Space: 66GB RAID 5, 3 stripes, Stripe Size 64kb, Wide Termination (one 34,578MB Seagate ST336607LW, two 34,938MB Seagate ST336807LW ) PS/2 Keyboard PS/2 Mouse Two DB 9 pin serial ports One 25 pin lpt port 2 USB ports Serverworks One onboard Intel NIC 10/100M, MAC 00B0D0D094E8 Card Slots: Slot 4, planned to place TDM404E in this slot Slot 5, Intel NIC 10/100M Slot 6, Intel SCSI ---------------------------------------------------------------------------- So, is the above sane or am I going to have to stay up all weekend? -seriously, let me know if you see looming disaster (and it'd be useful if you told me the specific disaster you see and how to avoid it).
