Hi, i suspect the problem between two blackberry devices are simple: one of them send a "end of media" or "AMR header" each 30 secs. I try yesterday to determine if that is a possibility with no results. But i'm sure the problem is on the data sended when a two blackberry devices stablish a call. cheers > From: address@hidden > Date: Wed, 18 May 2011 15:51:57 +0200 > To: address@hidden > Subject: Re: [Linphone-developers] linphone blackberry error 523 on device > > Hi Jean, > > unluckily I've not solved the problem.
