[asterisk-users] One way audio with Grandstream HT503

Mon Feb 1 14:33:50 CST 2010

Hello list !

I'm having one way audio on incoming and outgoing calls. Outgoing audio
works fine, incoming audio is not working.

My setup is the following :

incoming calls :
PSTN -- FXOport -- HT503 -- WANport -- Asterisk -- WANport -- HT503 (the
same) -- FXSport -- DECTphone

outgoing calls :
DECTphone -- FXSport -- HT503 -- WAN-port -- Asterisk -- internet
(VoIPprovider)

I've done a TCPdump on the Asterisk-server :

18:20:22.372404 IP my.asterisk.server.be.sip > vds.server.net.sip: SIP,
length: 423

In rtp.conf the range 20000 --> 20100 is defined.

On the Asterisk server I have opened port 5000 --> 50000.

But still one-way audio... Something with the download of the RTP-stream
coming from the VoIPprovider I think. Upload (outgoing audio) is no
problem.

Codec is alaw for both ways.

Any suggestions ??

Kind regards,

Jonas.
