outbound ring tone

im not sure what to call this so i cant really search for it.

when i dial out using my GV account instead of hearign a typical ring pattern like you might with a regular phone line i hear a long beep for each set of rings.

is there a setting to change this sound to something else like a standard ring pattern?

That sounds like the ring back signals, and are controlled by the other end, meaning there's nothing you can do to alter it. 

I'll leave the door open a bit on this to say some VOiP phone calls give a signal before the called party's phone reports ringing, and that may be what you are hearing. However on all my GV calls I immediately hear the ringing, with a different cadence/pattern for calls to the UK and Australia, for example.

It's known as Ring Back, or Ring Back Cadence or Ring Back signal or tone.  Look up the international standards for this, ITU Ring Back signals. Different countries have different signals/patterns/cadences, and it can be interesting to hear the sounds you're not always used to, Italy and some Eastern European countries have interesting patterns. Youtube has some examples.

I think this is specific to the Obi.

Utilizing GV without goign through the obi results in a normal sounding ring tone. The issue only arises when trying to route GV calls through the obi.

CoalMinerRetired:
It's a worldwide standard that the ringing you hear when placing a call is generated by the called party's equipment, not by the calling party's equipment.  I don't believe there is any mechanism, in an OBi or otherwise, that intercepts a call being setup and generates a tone, a beep or any signal.

My guess is what you are hearing is something happening between your dialing and when GV is able to send the ring back tones, or for reasons unknown there is significant latency between when you finish dialing a call and when your OBi gets the ring back signals. 

A few things to try, see if any make a difference:
Do you press # at the end of each call you dial? That makes any dialed numbers process immediately.
In the OBi only, change the DNS servers to use Google's, 8.8.8.8 & 8.8.4.4.  Or better yet use this grc.com tool to test the your latency to different DNS servers: https://www.grc.com/dns/benchmark.htm.

You really want the above test from your OBi, but you can't do that. Which leads to do you have any QoS settings enabled in your router?

When you dial a GV # elsewhere and do not hear these tones, how are you placing that call, on a cell phone? Via the Call Phone icon in Gmail? Something else?

coldhammer:
its not a latency issue. all calls were made to the same three test numbers.

gigaset > obi202 via ip > gv > test number = long beep instead of ringing sound.
gigaset > obi202 via ph1 > gv > test number = normal ring tone
gigaset > obi202 via ip > alternate voip service > test number = normal ring tone
gigaset > obi202 via ip > obiLine > test number = normal ring tone

the above tests show that:
the gigaset is not the issue.
gv is not the issue
the issue only presents itself when routing an ip call through the obi to gv. This leads me to believe there is some sort of setting within the obi that is generating this beep sound instead of the standard ring tone for outgoing calls.
