Hi Steve,
Yes I am trying to get SER to resend the INVITE to priority 2 after
priority 1 timed out due to connection down scenario.
Thank you,
Paul

Are you trying to get the proxy server to re-send the invite based on
the SRV list or the phone?

Greger and all,
The URL does not really help. You will see my cfg script below is
already using rewritehostport with no port and the SRV name.
I also am not using t_on_failure as it should not be necessary
according the post by Klaus.
Heres my SRV table with the ranking priorities:
_sip._udp.vxml.pats.cisco.com SRV service location:
priority = 1
weight = 1
port = 5060
svr hostname = vxml-1.pats.cisco.com
_sip._udp.vxml.pats.cisco.com SRV service location:
priority = 2
weight = 1
port = 5060
svr hostname = vxml-2.pats.cisco.com
_sip._udp.vxml.pats.cisco.com SRV service location:
priority = 3
weight = 1
port = 5060
svr hostname = vxml-3.pats.cisco.com
pats.cisco.com nameserver = ns1.pats.cisco.com
vxml-1.pats.cisco.com internet address = 10.86.129.x
vxml-2.pats.cisco.com internet address = 10.86.129.x
vxml-3.pats.cisco.com internet address = 10.86.129.x
ns1.pats.cisco.com internet address = 10.86.129.x
Thanks anyone for any help,
Paul
