Configurating Asterisk with SIP trunk via proxy (sip.conf) [resolved]

Asterisk Asterisk SIP
1

Hi,

I’ve got truble while configurating Asterisk.
I had to replace my S0 to a SIP trunk today.
My Provider mailed me my new user data with my user id, passwor, registry and proxy.
I added the following configuration so my sip.conf:

[vsenet]
type=peer
host=sip.vsenet.de
outboundproxy=10.199.27.21
port=5060
username=MY_USER
fromuser=MY_USER
fromdomain=sip . vsenet . de
secret=MY_PASSWORD
dtmfmode=rfc2833
insecure=port,invite
canreinvite=no
registertimeout=600
disallow=all
allow=alaw
allow=ulaw
context=public

and

register => MY_USER:MY_PASSWORD@vsenet/MY_USER

But I only got the following error:

Probably a DNS error for registration to MY_USER@vsenet, trying REGISTER again (after 20 seconds)
[Feb 12 21:54:17] NOTICE[1375]: chan_sip.c:15967 sip_reg_timeout:
– Registration for ‘MY_USER@vsenet’ timed out, trying again (Attempt #74)

To check my user data I tried them on the same machine with X-Lite:

User ID: MY_USER
Domain: sip . vsenet . de
Password: MY_PASSWORD
Display name: VSE
Authorization name: MY_USER
Domain Proxy:
Checked „Register with domain and receive calls“
Send outbound via: Proxy
Address: 10.199.27.21

Dial plan: #1\a\a.T;match=1;prestrip=2;

X-Lite works with incoming and outgoing calls.

Asterisk Version: 15.2.0

Thanks for help

I believe you need to fully qualify your register string.

Do you mean this: register => [peer?][transport://]user[@domain][:secret[:authuser]]@host[:port][/extension][~expiry]?

Which part do you think I missed?

Or do you mean a FQDN? If I replace it with: register => MY_USER:MY_PASSWORD@sip.vsenet.de/MY_USER

I got:

[Feb 12 22:36:29] NOTICE[1375]: chan_sip.c:15967 sip_reg_timeout: – Registration for ‘MY_USER@sip.vsenet.de’ timed out, trying again (Attempt #5)
[Feb 12 22:37:49] ERROR[1375]: netsock2.c:303 ast_sockaddr_resolve: getaddrinfo(“sip.vsenet.de”, “(null)”, …): Name or service not known

Thanks

That looks better.

Do you have working DNS on your asterisk box?

Can you resolve that host from your systems shell?

DNS is working. X-Lite on the same machine works.
But the Record for sip . vsenet . de is not public.

ping sip.vsenet.de
ping: cannot resolve sip.vsenet.de: Unknown host

It’s only available through the proxy 10.199.27.21

I don’t know if it’s possible to specify a proxy for a registrar string.

Instead I’d suggest adding a callbackexten option to your peer and seeing if that works to make it register outbound.

7

I’m not sure what you mean.
Could you give me a litte example?

Thanks
Marc

[vsenet]
type=peer
…
callbackexten=MY_USER

Ok, Thanks.
Resolved the Problem a few minutes ago:

I had to add sip . vsenet . de to my local DNS (or /etc/hosts) with IP of the Proxy.
Now it works.

Thanks a lot for your help
