FMG to Flashphone - No audio in outgoing stream

Hi everyone,

i'm currently working on a flash softphone and i'm currently able to route sip calls made to FMG to the flashphone

on a call i can hear fine the other end but the other end is not able to hear my microphone activity.

I've taken multiple steps to assure everything is going correctly clientside as follows:

Added an activity handler on the microphone : There is voice activity

When publishing the stream, i tried to publish with "record" and the recorded stream does include the voice activity

What i think is going on is that something on FMG side is not routing my call correctly maybe?

Here is the current workflow of my app:

I hit a "call me" button

the flash phone connects to FMS and asks for a phoneID

it gets the phoneID and by webservice initiates a sip call phoneID@FMG.ip

The FMG gets a sip call with that phoneID and routes it to the FMS which sends it back to the flashphone with an onLeg event

When receiving the onLeg event, the flashphone accepts the call (and also plays the incoming call with netstream.play()) and does two things, pushNewStream with the phoneID and a netstream.publish() with the phoneID

What i thought could be the problem is that when receiving the onLeg event from FMS, the stream name is not equal to phoneID but something like fmg/telephony/1, is that normal? or should it also be the phoneID?

Anyways if someone has an idea of what could be going on I would really appreciate it as i'm really going nuts here..

Correct answer mhaltali

Hi, i was able to resolve the issue!

for anyone in this scenario here's what was happening to me

I was first using an AMS & AMG 5 but downgraded to FMS & FMG 4.5 because of a bug in the AMG with DTMF

but my telephony app was using the AMG 5's TelephonyLib and this caused an error when communicating with the FMG 4.5

Too bad there wasn't a clearer message then "Invalid message received, dropped"

Anyways i hope this can save someone some time

I've made some progress on this,

from what i found the audio stream going from the FMG to the Flash player, there is two clients on it:

-1 publishing the stream (FMG)

-1 viewing the stream (Flash player)

But on the outgoing stream from flash player to FMG there is only one client:

-1 publishing the stream (Flash player)

Nobody is actually viewing the stream! The FMG is not registered to this stream and explains why no audio comes through the call from FLASH to PHONE.

But i cant figure out why, here are the FMG logs for the call

core.00.log:
