i’m experienced a strange behavior in my asterisk box 1.4.42 installed from binary rpm packages on centos 5.6.
In my sip.conf i have
register => username:password:firstname.lastname@example.org:5060/username
callerid=Interno 401 <401>
Well, if i have internet connection so that the name voip.eutelia.it is resolved everything works fine, but if i the name is not resolved client 401 doesn’t register.
netstat -u -p says me that asterisk is “listening” on 5060
tcpdump says me that client send a sip packet trying to register, but i cant see any sip packet from my asterisk box to the client.
If i comment the registration to eutelia and restart asterisk 401 can register and everything work fine even if the box can’t connect to internet.
Someone can help me?
Thank’s in advance
