Dear everyone, I am new to the mailing list and the asterisk system. I am looking for suggestions to start a VoIP test lab and I am seriously interested in the asterisk solution. After some homework, this is the end to end system that I come up in mind: 1. Two PCs running asterisk: Intel Celeron, 833MHz, 256M memory 2. Each PC with one Wildcard T100P Single-Span T1, one Wildcard TDM400P Quad-Port FXS PCI 3. 5 3com SIP phones plus software phones 4. And I like to interconnect these two PC through Ascend 4000 WAN router. Will the system work? The test lab will probably be expanded later and need: 1. WAN simulator 2. Asterisk system to other vendor system: Nortel, Cisco. 3. E1 support Do you see any potential incompatibility in this initial system for future needs? Thanks! Lisa
