[SR-Users] RTPEngine QoS statistics and leg labelling

[Alex Balashov]

Well, both the 'query' command and final logging confirm that the labels
are correct for the respective from-tags:

But for some reason, the "B" PVs just aren't being populated, even
though I use the labels: 

	if(check_route_param("proxy_media=yes")) {
		$avp(rtpengine_a_label) = 'outbound';
		$avp(rtpengine_b_label) = 'inbound';

		rtpengine_delete();

		route(LOG_RTPENGINE_STATS);
	}

And have the PVs referenced:

	modparam("rtpengine", "mos_A_label_pv", "$avp(rtpengine_a_label)")
	modparam("rtpengine", "mos_B_label_pv", "$avp(rtpengine_b_label)")

This is using rtpengine:mr5.5.3 and kamailio:5.1 latest clone.
