My Pulse Rotary phone cannot dial out. PLEASE HELP

[Vinhvinny]

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?

I found this with a Google search.
I don't know if this will work with an OBi, so buy at your own risk.

Just confirming that there is no configuration setting on OBi ATAs which makes them recognise digits from loop disconnect dialling. An external converter is the only option.

I played around with a rotory phone from the 60's. I had to up the ring voltage to get the bells to work. If you hook up multiple rotory phones, the Obi may not be able to ring them all.
