The attached patch is based on Menyus's SCTP multihoming patch (posted
It adds multiple SCTP homes and RFC 5061 support.
One can use the following arguments while running sipp:
-multihome : Set multihome address 1 for SCTP
-multihome2 : Set multihome address 2 for SCTP
-multihome3 : Set multihome address 3 for SCTP
-addip : Enable Dynamic Multihoming using ASCONF (RFC 5061)
By setting "-addip 1", sipp will send ASCONF chunks to establish
multihoming with the peer.
When addip is 0, it will send all the IP's within the INIT chunk in
the IP address parameters.
