SIP protocol help

hello everyone, I have loadbalancing configured on my network with 2 connections, but i have a problem if someone on my network tries to make a call using their magic jack or anything using the sip protocol and it chooses the wan2 connection the call doesnt work but if it chooses the connection wan1 it works well.

Is there a way i can forward all the SIP requests to the connection wan1 .

Please let me have these configs.

Thanks in advance.

Run a packet capture using Wireshark or the MikroTik Packet Sniffer and capture traffic coming out of the MagicJack.

Some VoIP boxes set DSCP values on SIP and RTP traffic. If the MagicJack is doing this then you could write a rule to match all packets with that particular DCSP value then exempt it from your load balancing rules and send it straight out WAN 1.
