Hi,
I agree they should have shared nonce, but still I think FS should use same IP for initial and challenged invite unless TTL for domain is not expired.
Is there a way to force it to such behaviour? I've tried with fs_path but seems this does not work for challenged invite neither
Somebody posted bug FS-8820 on same case but with different carrier.
Regards

if they are doing nonces on a shared realm, they should be sharing those nonces across their cluster. If they are not, every time it hits a diff member of the cluster you will get a stale nonce and have to go through that juggle again. This is just a side effect of how sip auth works.
Hi,
I'm having problem setting-up trunk with provider who does have muliple sip-proxies with not shared nonce db.
sip.freeconet.pl resolves to 3 diffrent IP and FS does not cache/remeber IP that send back request.
So we have a case
FS->P1: Invite
P1 -> FS -> 407 + nonce
FS does again DNS lookup and
FS->P2 Invite with nonce from P1
P2->FS 407
FS fails call.
Is there a way to force FS to send all messages within dialog to one IP only ?
