[cisco-voip] Server-groups and failover...

[Anthony Holloway]

First off, I'm wondering why it says "no ipv4" in front of your two
addresses.  That might be your problem right there.

Secondly, I'd recommend putting an explicit preference on your entries,
it's just better for everyone, and you don't get a credit back from Cisco
for saving on a few ascii characters by implicitly using the default.
Plus, if the default is 0, which it is, then your next preference should be
technically 1.  But then having nothing and 1 seems silly, because if pref
1 is actually pref 2, then well, might as well call them pref nothing and
pref 8.  I digress.

You might not have failed over, because you might not have provided the
system with the correction conditions to failover...E.g., you didn't wait
long enough.

No seriously, by default SIP failover occurs after 30 seconds.  Unless, did
you lower the retry count under sip-ua?  Or did you enable SIP options?  If
you enabled SIP options, have your confirmed that it's turned on correctly?

Can you share the output of the following commands:

show run | section sip-ua|sip.options-keepalive

show dial-peer voice summary

Feel free to redact what you need to, in terms of IPs or
usernames/passwords.  I am only looking for the features and settings for
retries and keepalives.
