I have found a totally weird method of getting this working.

I simply need to add another field to the sippeers database table.

Here's the table definition as I've been using it for months:

CREATE TABLE `sippeers` (
  `DDI` varchar(32) NOT NULL DEFAULT '',
  `name` varchar(80) NOT NULL DEFAULT '',
  `type` enum('user','peer','friend') NOT NULL DEFAULT 'peer',
  `fromuser` varchar(80) DEFAULT NULL,
  `defaultuser` varchar(80) NOT NULL DEFAULT '',
  `host` varchar(31) NOT NULL DEFAULT 'dynamic',
  `secret` varchar(80) DEFAULT NULL,
  `ipaddr` varchar(45) NOT NULL DEFAULT '',
  `port` mediumint(5) unsigned NOT NULL DEFAULT '0',
  `insecure` varchar(20) DEFAULT NULL,
  `context` varchar(50) DEFAULT NULL,
  `regseconds` int(11) NOT NULL DEFAULT '0',
  `fullcontact` varchar(80) NOT NULL DEFAULT '',
  `callbackextension` varchar(250) DEFAULT NULL,
  `regserver` varchar(100) NOT NULL DEFAULT '',
  `useragent` varchar(50) NOT NULL DEFAULT '',
  `lastms` int(11) NOT NULL DEFAULT '0',
  `qualify` char(3) DEFAULT 'no',
  PRIMARY KEY (`id`),
  KEY `name_2` (`name`)

If I do the following:

alter table sippeers add column anything int after qualify;

(I've called the column "anything" to emphasise that the name appears to be 
entirely unimportant)

then all of a sudden, the lastms field contains useful and sensible values.

Is this a bug, or is there something wrong with my original table definition?
