Question, when does a value get inserted into the ser.location table’s received column. We have some UA’s with a contact like value and some with null values – different devices (Polycom 331/450/55, Grandstream 286/486) behind the same firewall. I’m just curious to know why some have a received value and some don’t. Thanks, Bill SER 2.0 Linux 2.6.9-78 x86_64 MySQL 5.1.30
