Realtime User has error at Register/Unregister

I have errors at register/unregister sip user from Mysql table (Realtime):

ERROR[1238]: netsock2.c:269 ast_sockaddr_resolve: getaddrinfo("", "24075^LinphoneIPhone/2.0.2", ...): Servname not supported for ai_socktype WARNING[1238]: chan_sip.c:15763 __set_address_from_contact: Invalid host name in Contact: (can't resolve in DNS) : '^LinphoneIPhone/2.0.2'
Register log 1:
Register log 2:
Unregister log:
Data in MySql: (sorry for this table)

User from sip.conf doesn’t have this problem.

Sorry for stupid question, but what should I do to fix this errors?

well , the same problem i have. if u use a realtime sip friends after reload all registeration gone. so that anyone cannot call any1. after delete fullcontact from database , my problem is solved. because it reads “^LinphoneIPhone/2.0.2” like that. and seacrh hostname and cannot find.
when we delete fullcontact , it tries update fullcontact and get ERROR “cannot update fullcontact” but everythin works right. it is my solution.

or set fullcontact length to ‘90’ in database.

Thank you!
It’s works!!!
