[asterisk-users] PJSIP configuration question

[Dan Cropp]

I corrected my local_net setting (based on advice from network admin).

I have tried several different values for the from_user and still have the same problem.

Asterisk receives the OK from Vitelity.
Asterisk sends the ACK (without a Contact header).
Vitelity doesn’t seem to process it, so they send an OK again.

The OK receive, Transmit ACK occurs 4 times.
A short while later, Vitelity hangs up on my cell phone.

Asterisk is never told the call  is gone.

If I hangup the call from Asterisk side,
Asterisk sends the BYE message.
Vitelity responds with a “SIP/2.0 481 Call leg/transaction does not exist”

Again, the trace indicates the ACK message is missing the Contact header.

Additional note: the network admin is asking why the local_net, external_media_address, and external_signalling_address are needed.  He wrote me…“You should NOT have to know your public IP.  The firewall should be doing fixup commands to change the values in the packet”

Thanks George.

I will correct my local_net in the morning.

Vitelity chan_sip settings I have working, do not have a fromuser.
sip.conf settings...

I think you can actually specify anything, it just has to be populated with something other than a sub-account username.

I am not sure if I entered the correct settings for the transport information.
For the local_net, I entered my local ip address, but no mask.  I will check with the network admin so he can verify the settings I entered.

You need the network and mask.  For example if the ip address and mask of the test machine is 192.168.0.1/255.255.255.0<http://192.168.0.1/255.255.255.0> then the correct entry would be 192.168.0.0/24<http://192.168.0.0/24>.

One minor detail, we are using ip authentication.  When Vitelity changed my account from user based authentication to IP based authentication, they stopped including a user for the account.

Should these settings work without the from_user (IP based authentication) or do I need to get the account name from Vitelity?

You definitely need the master account login username.  If you has this working with chan_sip, then try the 'fromuser' from sip.conf and user is from_user.




Have a great day!
