If you have a "normal" home broadband connection (DSL, cable, or fiber), something is very wrong. For example, even the slowest (6Mbps downstream) service from SingNet advertises 512 kbps upstream. Conservatively, you should get 400 kbps useful (as measured by a speed test).
If you have a wired Internet connection, there could be a problem with your line, modem, or networking equipment. Or, your line might be saturated with unwanted traffic (malware, configuration issue, filesharing in background, neighbors leeching off your unsecured Wi-Fi, etc.) Log into your modem and look at the stats (noise margins, resyncs, retransmissions, total traffic, etc.) Once you get that fixed, you should enjoy excellent quality with G.711 (anything over 100 kbps on a speedtest should be fine, if you refrain from surfing while on the phone).
My apology for being confused by the other (US based) posters in this thread. For an echo test with an SG number, call +65 31581212. This is an iNum gateway. At the "welcome to iNum" prompt, dial 000000091#. The actual echo test server is in Belgium, so latency will be long. However, you can still make valid comparisons; test from your office and measure the delay. Then, test from your softphone through the OBi and your office PBX. The difference between those delays should be very close to the round-trip delay you'll experience when calling an SG customer on his landline.
If you have a wireless connection (cellular data, or fixed wireless), please supply some details. While not ideal for VoIP, it shouldn't be as bad as what you have tested.
I'm fairly close (Bangkok) and just tried
speedtest.net, selecting the first Singapore server (Telin). My DSL here is rated at 10Mbps down, 1Mbps up, and was able to saturate the line with that server.
