Looking for an experienced VoIP engineer who can build an iLBC<->g711 transcoder to be used in conjunction with our softphones (iOS & Android app). The transcoder would need to be able to transcode between iLBC and g711. The leg between smart phone and transcoder would be iLBC and the leg between transcoder and switch would be g711. In the case where the softphone does not offer iLBC, the transcoder would pass through g711. The core challenge of the problem is that the softphone will be configured with registration credentials for our hosted PBX and the transcoder will be set as the softphone's outbound proxy. The transcoder must allow registration requests to passthrough to the hosted PBX. We are looking for someone to propose and implement a solution.
