You are missing the instance (.3) and so the number of calls is above
max-bytes, and mrtg is discarding the value.

Here is the template that I use:
# First see if there are VOIP interfaces:
my %iftype;

if ($$router_opt{'interfaces'}) {
   foreach my $ifindex (sort {int($a) <=> int($b)} keys %$router_ref) {
        next unless $ifindex =~ /^\d+$/;
             my $i = $$router_ref{$ifindex};
             my $if_type = $$i{ifType};
             ++$iftype{$if_type};
        }
}
if ($iftype{81} +$iftype{102} > 0) {
   my $maxcalls = $iftype{81}+$iftype{102};
   my $target_name = $router_name.".call";
   $head_lines .= <<CALLS
#.....................................................................
# Voip Concurrent Calls
#

}
