OBi 110: how to call from landline abroad?

<< < (2/2)

ianobi:
I suspect that you are correct. However, it does seem odd that you can receive incoming calls ok on the landline.

It might be worth trying the OBi110 at another location - friends or family homes maybe. The land line does not need an internet connection to make it work, so it's just a question of plugging it in to a phone socket and providing power.

Lavarock7:
Normally here in the US if you pick up a phone line, you get dialtone and if you don't dial anything the dialtone changes to a beep beep reorder type tone. It is fast-busy here in the US.

If you do dial a digit (of the phone company THINKS) you dialed a digit, you will hear silence until the reorder tone.

Certain noise on the line or the chatter of a relay or switchhook (like a flash) can make the phone company think a digit was dialed, thus breaking dialtone.

In your last message you appear to be able to bring up the line but your touchtones are not going through. Perhaps there is an adjustment you can try for volume on inband (DTMF) tones on the phone configuration in the Obi.

I have done a number of searches for "parameters" and "standards" for your landline connections there, but see nothing online.  I was wondering if standars US phones work there, ring voltage, impedance, polarity, etc.
