Hi. Am new to this concept but have been requested to add VOIP capability to a small office phone system.
They currently have 4 standard analog lines running into a PBX feeding 16 phones, with all the usual features, call transfer call hold internal calls etc. would the following seem reasonable ? asterisk server:- ( what specs ) cat5 > broadband (VOIP) 4 FXO's for incoming PSTN lines ( TDM04B ? ) 4 FXS's for output to existing analog PBX ( TDM40B ? ) Leaving the existing infrastructure as is but inserting asterisk box as a filter between internal system & external PSTN lines so presumably a user could add a prefix to a number to have asterisk route the call via VOIP or no prefix to send over land based analog phone system ? I doubt they would wish at this time to replace their existing phone system with an all ip based system ( the cost of the ip phones would seem prohibitive ) Assuming the above sounds reasonable, is there any way to include a fallback system that would not disable the existing phone system in the event of the asterisk box crashing/locking etc. as dead phones is not an option ?? Many thanks for any help advice, as stated in the beginning asterisk and tele-comms is new to me although im experienced with linux sys-admin, networking etc. Many thanks Martin _______________________________________________ --Bandwidth and Colocation sponsored by Easynews.com -- 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
