First Answer Wins

Hi

I have an Android with sip phone installed and a sip phone at my office. Also my local number provider company
gave me a SIP to use my office number.

When I’m became online from my Android, office phone goes offline and won’t get back online until the reboot.

I have tried to make an Asterisk server to answer the sip account that I got from my provider and route the call
to Android phone or office phone. My point is the device that answers first, wins the call.

How can I do that ?

Thanks.

Separate the two device names by & in the dial string. This assumes that you have valid answer supervision.
