Some providers change the Contact header when replying the register. The provider says 200 OK for register but I got this: ERROR: uac [uac_reg.c:876]: uac_reg_tm_callback(): got sip response 200 while registering I think the problem is at https://github.com/kamailio/kamailio/blob/master/modules/uac/uac_reg.c#L744 In my case, the provider change the username part of Contact in register request: Contact: <sip:DID_NUMBER@IP_ADDRESS:5060> in reply: Contact: <sip:SiENC*DID_NUMBER**IP_ADDRESS*5060*@IP_ADDRESS> So if username is different, I will never get ri->flags |= UAC_REG_ONLINE; _______________________________________________ sr-dev mailing list sr-dev(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-dev
