I got a note this morning about the public availability
of TringMe's Mobile VoIP client (Beta). Although the MobileVoIP application was
available in a private beta since a few months, based on the user feedback, they made additional optimizations to ensure that one can get the best voice
quality in such an environment.

I personally wasn't part of the beta and haven't used their solution, but it's another interesting entrant in this very hot space.

The application is currently supported on several Nokia
devices which include E51, E60, E61, E61i, E65, E70, E90, N80, N81 (all
versions), N82 and N95 (all versions). They're committed to adding more phones and
platforms to the supported list. This is interesting to me and I can install and test on a few different Nokia phones, but I'm personally always looking for Blackberry applications too.

The application utilizes the underlying data network to initiate Mobile VoIP calls. While there are a couple of MobileVoIP applications already , what differentiates TringMe MobileVoIP is that calls can be made to and received from the all termination options that TringMe supports which include landline and mobile phones, SIP phones, Instant Messengers (Gtalk), Flash Widgets etc. This gives the user an extended range of flexibility to determine the best options for making and receiving a call from a mobile device.

For example, a TringMe MobileVoIP user can call another user on either MobileVoIP or Gtalk or even on our Flash widgets. Also, a TringMe user can configure his or her personal push-n-talk widget to connect to TringMe's MobileVoIP client. Anyone clicking on it will directly ring the Mobile Client. Similarly, a Gtalk user can call TringMe's MobileVoIP user by typing 'call <tringme username>' into Gtalk chat window (read more about our Gtalk support here). All this is in addition to making worldwide phone calls like other MobileVoIP solutions.

TringMe provides integration with their MobileVoIP solution using a published API. TringMe's MobileVoIP solution can be used by other VoIP providers by simply entering appropriate SIP settings in the user profile or using the API.

To use TringMe MobileVoIP on a supported Nokia phone, all you need to do is to point the web browser of your mobile device to http://tringme.com/tringme.sis . It will automatically download and install the TringMe MobileVoIP application. Once the application is installed, just login with TringMe credentials and you are ready to use MobileVoIP. No complicated settings or need to send any SMS to activate or initiate calls.

Once installed, you can start making calls through TringMe like your regular calls. Just dial, and choose the internet call option on your mobile and you are done.

Based on the beta users feedback, they decided to support MobileVoIP over both WiFi and 3G/2.5G networks. However, please note that due to the inherent nature of 3G/GPRS networks, the quality of service (QoS) over 3G may not be the most ideal for a clear voice call. However, working within the limits of the underlying network, our solution tries to extract the best QoS that it can. This is an interesting idea because many of the current providers are finding VoIP quality is pretty questionable on the existing 2.5G networks.
