I have a few very cool old rotary phones.
They are all pulse dialing phones. I bought an Obi using GV trying to bring them back to life. However, they can only receive call, they can't dial out.
When I dial the numbers, the I hear the pulse, then the dial tone still come back and after a few numbers the busy tone appears.
I know for sure the phones are not broken, the last time used they work.
Is there adaptor or any thing I can buy to make them work with obi?
