Residential 2-Line Account, 1 DID

Just thinking out loud
Sorry if this does not fit any calling model you may ever plan.

One DID 555-437-5555 with two(2) SIP channels registered. (2-channel ATA or two ATAs)

Map two ATA channels as:
SIP0 Address: SIP:5554375555@sip.voipo.com VOIPo
SIP1 Address: SIP:5554375555x1@sip.voipo.com ATA1
SIP2 Address: SIP:5554375555x2@sip.voipo.com ATA2



Hypothetical, just giving you more food for thought.

For a 2-Line Setup. (Call Hunt.)

If a call goes to SIP0
you then route it to SIP1 Address

If SIP1 is busy
you then route it to SIP2 Address

If SIP2 is busy
you then route it to vmail (No call waiting)



Hypothetical, just giving you more food for thought.

For a 2-Location Setup. (Ring in Parallel.)

If a call goes to SIP0
ring SIP1 and SIP2 Address (Two ATAs)

If both are busy or no answer
you then route it to vmail (call waiting enabled)
