[SR-Users] unsupported route_type 64

[Admin]

Hi,
 I am running Kamailio (4.4.0-dev2 (x86_64/linux)) with cgrates
real-time billing application. At the end of a basic call (prepaid to
postpaid), I receive the following error: 

ERROR:tmx [t_var.c:521]:pv_get_tm_reply_code():unsupported route_type 64
8(6740) DEBUG:tmx [t_var.c:526]:pv_get_tm_reply_code():reply code is <0>

What does route_type 64 mean? I checked the archive posts (FS#456) and
seemed to be fixed in branch 4.1 (part of 4.1.5).

Thanks.
