I tried to connect with an Xlite phone and everything was ok
Peer User/ANR Call ID Format Hold Last Message Expiry Peer
(null) 226029001055937 084690c94cdbd0a (nothing) No

2 sip peers [Monitored: 1 online, 1 offline Unmonitored: 0 online, 0 offline]

2

Is the issue inbound or outbound calls ?
Where is the sip configuration for this peer ?

also if you use x lite to test the sip credentials you used an username and password, which you should be using on the asterisk side with the registration string, in order the inbound calls to work assuming they send the calls to a SIP user instead of SIP URI

Hi,
sory i am pretty new to asterisk, this is my first asterisk system which i am trying to set up.
I am having issues with both outgoing and incoming.

here is what i tryed to write up in sip.conf

permit=0.0.0.0/0.0.0.0
type=friend
username=22602900105XXX@as1.romteleXXX.net
secret=24129188129XXX
transport=TCP&UDP
domain=as1.romteleXXX.net
host=as1.romteleXXX.net
bindport=5060
udpbindaddr=0.0.0.0
nat=force_rport,comedia
registertimeout=600
insecure=port,invite
dtmfmode=RFC2833
disallow=all
allow=G711A&G729
context=from-pstn-toheader
qualify=yes
trustpid=yes

and the inbound string
226029001055XXX@as1.romtelecom.net:24129188129XXX@as1.romteleXXX.net:5060

4

register string start with register=>
Is this really the username or you add the username with the server name ?

also you have some settings that you can improve like type peer instead friend to add more security, dont need to use insecure port, as this wont make any difference really with your issue, invite it is not needed if use remotesecret and remove the secret

I will suggest enable the sip debug with sip set debug on and try to debug a call

Here is what the ISP gave me :

Minimum requirements for siptrunk :

The SIP credentials must be configurable with:

  • The all service codes were using * and # characters, must be sent to VoIP platform in clear mode, the # char should send as it is.

  • FAX must working over G711Alaw as well as using T38.
  • Register Expire = 600 s
  • Session Expire =3600 s
  • Min Session Expire =90 s
  • Send Option =Enable
  • Proxy Server Port =5060
  • Registrar Server Port =5060
  • Register Retrying Interval = 60 s
  • Option Timer = 250 s

There is DNS issue here

Also the trace you displayed is not for a SIP call it is an OPTION request for peer 300 nothing related to this issue

8

That hostname does not resolve. It also does not have an SRV record.

9

The ISP sugested that for Asterisk systems i should do a map-area in etc/hosts which i am not sure if i did it correctly :
127.0.0.1 Sangoma-PBX localhost localhost.localdomain localhost4
::1 Sangoma-PBX localhost localhost6
::2 92.87.198.XXX as1.romteleXXX.net

10

can you please tell me how to fix that like i said i am really new to Asterisk

many thanks

11

You did not place it into /etc/hosts correctly, it would be a line like:

92.87.198.XXX as1.romteleXXX.net
1 Like
12

127.0.0.1 Sangoma-PBX localhost localhost.localdomain localhost4
::1 Sangoma-PBX localhost localhost6
92.87.198.XXX as1.romteleXXX.net
i think now is correct

13

Now on peers i have this message

Telekom/226029001055XXX@a 92.87.198.XXX Yes Yes A 5060 UNKNOWN

14

Should i try to replace the domain with the IP address ?

as1.romteleXXX.net with 92.87.198.XXX

15

You can if you want to… but it is now resolving and the peer has info. What happens now if you try to use it?

Asterisk isn’t getting a response to the SIP OPTIONS. You’d need to ask the remote side if the IP address is correct, and why they aren’t responding.

Some SIP mis-implementations simply do not respond to OPTIONS. Asterisk will accept even failure responses, and any valid SIP implementation should produce at least a failure response, even if it has no idea what OPTIONS means.

Hi all sorry for my late reply, but it seems like when i am new user i can’t post more than 22 reply in 24hours,
