No errors as far as I can see, ACKs go thru just fine. Digging further it seems that the problem is not handling these re-INVITEs in general but only the ones from a test trunk from a new provider. Following re-INVITE fails (10.10.48.129 is external SBC, 10.0.36.178 my 4.1 "SBC" and 10.0.32.40 the 4.0 register server with topoh, attached the full dialog): # U 10.10.48.129:5060 -> 10.0.36.178:5060 INVITE sip:172.19.162.1;line=pcs- mp4KWiTsxRmtEAM3WGysx7y3xGnoxAxtuAxSuA7KEsktxGZKWgQfZD6smqlf9Gttzjy*;alias=10.0.32.40~5060~1 SIP/2.0.

If inconclusive I'll dig some further on the register server during off peak moments. Calling the same endpoint but simulating with a SIP phone (natted) to 10.0.36.178, onhold works as expected.
