What are the supported codecs?
G.711 (μ-law / pcmu) , G.729 and GSM.

What codec should I use?
For best sound quality, if you have the bandwidth available, we recommend G.711u. However, you can still maintain an excellent voice quality and lower bandwidth usage with codecs like G.729.

What are the supported protocols?
We support SIP and IAX2.

Can you give me some details about these different protocols?
The Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol for creating, modifying, and terminating sessions with one or more participants. These sessions include Internet telephone calls, multimedia distribution, and multimedia conferences." (cit. RFC 3261). It was originally designed by Henning Schulzrinne (Columbia University) and Mark Handley (UCL) starting in 1996. The latest version of the specification is RFC 3261 from the IETF SIP Working Group. In November 2000, SIP was accepted as a 3GPP signaling protocol and a permanent element of the IMS architecture. It is widely used as a signaling protocol for Voice over IP, along with H.323 and others.

IAX is the Inter-Asterisk eXchange protocol used by Asterisk, a dual licensed open source and commercial PBX server from Digium and other softswitches and PBXs. It is used to enable VoIP connections between servers, and between servers and clients that also use the IAX protocol.

IAX now most commonly refers to IAX2, the second version of the IAX protocol. The original IAX protocol has been deprecated almost universally in favor of IAX2

Source and more information: Wikipedia

H.323 is an umbrella recommendation from the ITU Telecommunication Standardization Sector (ITU-T) that defines the protocols to provide audio-visual communication sessions on any packet network. It is currently implemented by various Internet real-time applications such as NetMeeting and Ekiga (the latter using the OpenH323 implementation). It is a part of the H.32x series of protocols which also address communications over Integrated Services Digital Network (ISDN), Public switched telephone network (PSTN) or Signaling System 7 (SS7). H.323 is commonly used in Voice over IP (VoIP, Internet Telephony, or IP Telephony) and Internet Protocol (IP)-based videoconferencing. Its purpose is thus similar to that of the Session Initiation Protocol (SIP).

What protocol should I use?
We recommend SIP. However we fully support IAX2

What type of equipment is required?
Any type of software or device (unlocked) which support SIP or IAX2. Including free softphones such as X-lite, free open source PBX Asterisk, Voxalot, Trixbox distribution, VoIP ata's and VoIP phones, Hardware CISCO VoIP switches etc. Basically, any hardware or software that supports one of the 2 protocols we offer.

How come the quality of voice on the phone suddenly degraded?
This situation could happen if you or someone in your network is downloading a big file which occupied large amount of your internet bandwidth and that will affect the overall voice quality of your phone calls.

What is the difference between Value and Premium Route for international destination?
Value route is one of the best quality carriers that we could find and target at clients who are looking for the best prices without any volume commitment.
Premium route is routed through established and renowned tier-1 carriers that can deliver the same destination, at a price that is little higher than our value route option. This is the default routing selection for our clients to assure best quality.
To override account setting, you can dial your international destination as follows:
033+Country Code+number: International Value Route
044+Country Code+number: International Premium Route
