Hello, this could be ip address of the different interface on the same box. I think it works like expected. The only exception would be if the sip peer ignores the icmp packet unreachable. But I doubt this is the case. Anyway you get problems also when calling to LTE phone without using sip provider.
Let first concentrate on these calls LTE to LAN. Are you sure you do not block incoming icmp unreachables? At least verify type 3 subtype 4 is enabled. If it is, I have no clue what is going on.
