Hello

I’m having proplem with “no audio” on sip phone grandstream GXP2130

The 3 sip phones are on the same netword of asterisk (192.168.0.0/24)

here my sip.conf:

[general]
allowguest=no
port=5060
bindaddr=0.0.0.0
nat=yes
disallow=all
allow=ulaw
allow=alaw
allow=gsm
context=sipin
language=it
externhost=prato.intellis.it
localnet=192.168.0.0/24
realm=sip.messagenet.it
rtptimeout=60
rtpholdtimeout=300

[phone1]
deny=0.0.0.0/0.0.0.0
secret=******
dtmfmode=rfc2833
canreinvite=no
context=outgoing_context
host=dynamic
trustrpid=yes
sendrpid=no
type=friend
nat=yes
port=5060
qualify=yes
qualifyfreq=60
transport=udp
encryption=no
callgroup=
pickupgroup=
permit=0.0.0.0/0.0.0.0
callerid="phone1" <620>
callcounter=yes
faxdetect=no
username=phone1

[phone2]
....

This is the first time i’m using grandstream phones… what I miss?

thank you

First of all I’d remove the deny/permit entries for the peer, since they contradict each other. Second, I’d check the Asterisk console at the moment of the call for clues, increasing the verbosity if necessary.
