Is there there a way to get the sip-ua in the ISR to react to, for example 5xx or 4xx responses from returned after and INVITE? i.e. can/will the sip-ua fail-over to an alternate host/target returned in DNS SRV resource record on receipt of a 5xx or 4xx response?

ISR Router won't act as SIP-UA .

Not so sure my 28xx would a agree with that statement.

Do you mean to have an alternate (secundary) target IP in case the first one fail, I have a configuration to do that but not sure if it's what you are looking for.
Let me know

I would be interested in this. At least to compare with what I have done today with my DNS SRV approach. Unfortunately I have had a TAC running on this for a little while now and I have finally had confirmation that sip-ua in the ISR will only failover to an alternate target up no response i.e. not on receipt of a 503 meessage for example.
Thanks

Not sure about the SIP message 503, I had done this long time ago and it worked with a 2801 even in the no response from fist ip address. Try this configuration...
