- SIP Retransmission Problem

Hi all, I have a problems with asterisk I configured a number eutelia for so I ring an internal

the file is as follows:


# sip.conf

Register: 0707732332:xxxxxxxx@voip.eutelia.it/0707732332
registertimeout20
registerattempts10

[eutelia]
type=fiend Xlanguage=it context=fom-eutelia host=voip.eutelia.it dtmfmode=rfc2833
directmedia=no fromdomain=voip.eutelia.it fromuser07732332
defaultuser07732332
insecure=invite qualify=yes secret=xxxxxxxxxx disallow=al allow=ulaw allow=aaw

# extensions.conf

[from-eutelia]

exten => 0707732332,1,NoOp same => n,Dial(SIP/1000,45)
same => n,Hangup

from cli:

the call drops after 4-5 seconds can you tell me what do I go to edit why this doesn’t happen?
I also disabled iptables in order to avoid any problem (although it seems properly configured)

Thanks in advance

    Hi Paolo,

    I had yesterday a similar problem and it was caused by a misconfigured IP address in extensions.conf that I forgot to update after changing some IP addresses in my network.

    Check the network connectivity between you Asterisk host and “1000”. Double check that the IP address is correct. Use tcpdump to see what’s going on the wires.

    Good luck!
