We are wanting to install an Asterisk SIP Server. We want to terminate all incoming calls onto this and thereafter route the same over Broadband to the user who will answer the same using a SIP phone. We want the flexibility to terminate Digital Analog and VOIP lines onto the EPABX.
We also want an interactive IVR.
We are looking at having three incoming lines and have three outgoing call lines.
The outgoing call shall be a VOIP call originating from a SIP Phone and shall through the EPABX go to either a VOIP (SIP) Phone or an analog line / digital line.
The volume includes call originating at different places and landing on the SIP Server.
Volume: To start with there will be fifteen users which will increase to 75 outbound callers.
I shall be grateful if selection of hardware is helped with.
Look forward for help and assistance in selecting the best solution.
Also look for advise on which are the best Broadband service provider in nirth America and cost effective.
We are considering Vonage any other suggestions on solutions with best voice quality and cost effective that other members have experience shall be very helpful to avoid mistakes.
