Hello. I'm Melih from Turkey. I'm database administrator, but I work koha for SIP integration to configure. I can connect SIP with koha when they are on same server. Now SIP is in different server and koha database is in different nodes. I inserted user and give permission. But I can't test via telnet. it errors when I login via telnet. '93'. What may the problem be? thanks for help. my error Sip::MsgType::new('C4::SIP::Sip::MsgType', '9300CNdevs...', '93'): seq.no '0', protocol 2 Jan 8 10:55:32 koha-web48 koha_sip[13585]: Sip::MsgType::_initialize('Login', '00CNdevsip2|COdev123|CP', 'A1A1', '2', ...)
