Hey Daniel,

Thanks for so fast feedback. I have doublecked again the config:

If it helps, here are my complete settings:
"""
# ----- dispatcher params -----
modparam("dispatcher", "list_file", "/etc/sbalancer/dispatcher.list")
modparam("dispatcher", "flags", 2)
modparam("dispatcher", "dst_avp", "$avp(dsdst)")
modparam("dispatcher", "grp_avp", "$avp(dsgrp)")
modparam("dispatcher", "cnt_avp", "$avp(dscnt)")
modparam("dispatcher", "attrs_avp", "$avp(dsattrs)")
modparam("dispatcher", "hash_pvar", "$avp(dshash)")
modparam("dispatcher", "ds_ping_from", "sip:SBalancer(a)mydomain.com")
modparam("dispatcher", "ds_ping_interval", 30)
modparam("dispatcher", "ds_probing_threshhold", 3)
modparam("dispatcher", "ds_ping_reply_codes", 
"class=2;code=403;code=488;class=3")
modparam("dispatcher", "ds_probing_mode", 1)
"""

Calling the logging block happens right at beginning, so not possible to 
overwrite the avp.
"""
request_route {
	#check antiflood before anything
	route(ANTIFLOOD);

	# Detect if requests are from internal network
	if ds_is_from_list() {
		xlog("Request coming from SCloud");
		$avp(s:authType) = "INTERNAL";
		$avp(s:authUser) = $hdr(X-AuthUser);
		xlog("Checking grp_internal, having: $avp(dsgrp)");
	}
"""

Result the same ( I am sure ds_is_from_list matches since I get the 
first xlog correctly):
"""
Aug 15 12:36:07 PrxyDev /usr/sbin/kamailio[2973]: ERROR: <script>: 
Request coming from SCloud
Aug 15 12:36:07 PrxyDev /usr/sbin/kamailio[2973]: ERROR: <script>: 
Checking grp_internal, having: <null>
"""

Thanks again,
DanB
