DX Voice Streaming (paging) Issue

“I am facing an issue when trying to send voice stream between 2 phones [ Cisco DX 650 phone and  any other Cisco IPphone ex. 9971]

As I am using Java Media Framework to record, and play the voice over IPphones (XML)

The voice stream file format is:

String encoding = ULAW_RTP

double sampleRate = 8000 Hz

int sampleSizeInBits = 8bit

int channels = 1

int endian = Mono]

Considering for [Xml IPphones] JMF detects only sound at 8000 Hz, and for [DX Phones] most common that android devices can’t record voice with sampleBits = 8bit.

I changed the voice recorded from Dx phone to satisfy the above format and change the sampleBits to be 16 for both [recording from DX and play on Xml ] but the issue is still exist and the file doesn’t accept to play and vise verse [ recording from xml and play on DX].


Please advise.
