[Serusers] route one call to two UA's?

[Jev]

Hi all,

Im replacing an old analog PBX with cisco ATA's, ser and a vega 50 BRI.

Currently, on the old system, when some one rings the PSTN number, it 
goes through and rings two different phones (one upstairs, one 
downstairs), and the first person to answer the phone gets the call.

Now, I need to replicate the behavior with ser, and the ata 186's. Has 
any one attempted this type of behavior? Is it within the capability of sip?

Thanks,
-Jev
