_______________________________________________Hi,I'm answering as the author of libosip & libeXosip ;)Linphone, in your case is based on eXosip.Linphone removed eXosip2 years ago and thus, you usea very old linphone and very old eXosip2 version..Anyway, whatever versions of eXosip2, it needs to be used that way:i = eXosip_listen_addr (ctx, IPPROTO_UDP, NULL, port, AF_INET, 0);if (i!=0){eXosip_quit(ctx);fprintf (stderr, "could not initialize transport layer\n");return -1;}If eXosip_listen_addr is failing nothing can be done with eXosip2, and " create transport layer first" logswill happen for some API which can't be used in that state.If the socket can't be created, the above API will fail. So a usual scenario is to have the port already used.A simple way is to choose another port when this is happening and I guess this old version of linphone wasn'tdoing that:i = eXosip_listen_addr (ctx, IPPROTO_UDP, NULL, port, AF_INET, 0);if (i!=0)i = eXosip_listen_addr (ctx, IPPROTO_UDP, NULL, 0, AF_INET, 0);if (i!=0){eXosip_quit(ctx);fprintf (stderr, "could not initialize transport layer\n");return -1;}RegardsAymericLe lun. 5 oct. 2020 à 12:28, David Villasmil <david.villasmil.work@gmail.com> a écrit :Not an expert here. But many moons ago, I was playing with pjsip and got the same. You must create the socket first, make sure the ip assigned is correct.--On Mon, 5 Oct 2020 at 06:47, Pavithra Mohanraja <pavimohan3004@gmail.com> wrote:Hi Jan,Sorry for the delayed response. I guess the issue is because of UDP transport, which my kamailio is not accepting. Because the same scenario is reproduced when I change my pjsip configurations to udp instead of tcp. But linphone gives me the following error if I tried to connect using tcp.ortp-error-wrong state: create transport layer first

Hmm, nothing obviously wrong. Is there anything in Kamailio's
logs? Are you sure REGISTER reaches kamailio? Can you run tcpdump
or even better sngrep on kamailio server?

Hi Jan,
I have also tried as u suggested with reg_proxy only with
sip server name, could not obtain any positive changes. I have
also attached the debug logs, please have a look and suggest
for any changes. Thanks in advance.
Sorry, I am not that good in linphone configuration file
so I may be wrong, but it seems to me that reg_proxy
should only contain uri of the server, not the user part.
Moreover, I have definitely more options there but not
using it as an IMS.
Mine is a bit more wordy:
[proxy_3]
reg_proxy=<sip:sip.server.here;transport=udp>
reg_identity=sip:420123456789@sip.server.here
realm=sip.linphone.org
contact_parameters=message-expires=604800
quality_reporting_collector=sip:voip-metrics@sip.linphone.org;transport=tls
quality_reporting_enabled=1
quality_reporting_interval=180
reg_expires=600
reg_sendregister=1
publish=1
avpf=-1
avpf_rr_interval=1
dial_escape_plus=0
privacy=32768
push_notification_allowed=0
idkey=proxy_config_voVF8eoXq46cJLs
publish_expires=600
nat_policy_ref=bUwFfNPHt40-miQ
Could you send the REGISTER message not being accepted?

Hi Jan,
I'm trying to connect linphone to my kamailio ims.
Only register request is sent from Linphone and no
acknowledgement is received. I'm attaching you my
linphonerc file. Please advise if any correction is
required in the configuration.
Hey, I have no problems with linphone (desktop
and mobile).
Could you be more specific on what you set up
and/or what the communication looks like when
using linphone?
Regards, Jan

Hi,
I am a newbie to sipclient Linphone. I know
this issue is not related with kamailio.Yet If
anybody have tried it before , kindly provide
me with some links or procedures to be
followed for call registration and
connectivity with kamailio since in my case,
request is going but response is not coming
back resulting in timeout issue.
This happens only in linphone.If i do the
samething in PJSIP/zoiper, call
registration and call establishment happens
perfectly fine.
Kindly help.
Thanks,
Pavithra
