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
ortp-error-wrong state: create transport layer first
ortp-error-eXosip: missing via header

Am I missing something really important? Please let me know. Thanks in advance.

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?

Regards, Jan

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?

Regards, Jan

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?

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
