Well, we have tested on a GSM device. But I guess most of recents BB devices support both CDMA and GSM. We know this version works pretty well on Bold series but not on Storm 2 9550 :-(Jehan,This is great news.Does this work with both GSM and CDMA versions of Blackberry handsets?
As BB applications are pure java, it is nearly impossible to encode/decode voice at the application level. For audio encoding, we rely on what RIM provides. So far only AMR-NB is available in realtime. Today, we think the best is use "server based" transcoding. We are thinking about providing a server with transcoding capabilities.Also, how hard is it to add other codec's (GSM, iLBC or Speex), as most IPPBXs don't support AMR?
Best regards,
Dan

Linphone for BlackBerry OS is a completely java rewritten Linphone leveraging on the java version of libblinphone API we have developed for Android. Simon has developed a java port of oRTP called jortp with adaptive jitter buffer. For sip, we have leveraged on sip-for-me, that we had to patch to fix a bunch of bugs. The core (I.E jliblinphone) is a strict implementation of the java version of linphonecore.
Linphone on BB only support AMR-NB because on BB 0S 5, it's the only available codecs with real time capabilities. So you have to find a sip provider supporting this codec.
Due to the lake of DNS api from BB OS5, sip hosts must always be entered as an IP address (I.E sip:address@hidden). Same for the proxy field in configuration view witch must be an ip address.
Binary installation is available from:
http://download.savannah.gnu.org/releases/linphone/blackberry/jlinphone-1.0.0/5.0.0/jlinphone.jad
Just open this URL from your BB web browser.
As usual, source code can be found at: http://www.linphone.org/eng/download/git.htmlContributions and feedback are as always welcome, use the mailing lists for that purpose.Cheers
