[cisco-voip] CME vs SRST

Sat Aug 18 20:41:44 EDT 2007

Carlos,

you may use CCME instead of SRST in case of CallManager failure. This
aproach provide you more features than SRST, like hunt groups, basic
ACD, and if configured properly, entire CallManager failure can be
totally invisible for the enduser.

Defenetly, my recomendation is to go to the CCME SRST Fallback support
because this can provide more features than SRST. You may find more info
on:

Subject: [cisco-voip] CME vs SRST

Can CME be used as a fallback from Call Mgr instead of SRST? I have
never thought so......but a previous admin has a CME config on a router
at a location that has the following excerpt: 

ephone-hunt 1 sequential
pilot 4700
list 4739, 4740, 4743, 4744
final 9XXXXXXXXXX
preference 3 secondary 7
timeout 16, 16, 16, 16
!
ephone-hunt 2 sequential
pilot 4799
list 4702, 4701
final 9XXXXXXXXXX
timeout 16, 0

The purpose of this config as explained by the business was when in
"SRST" (I know this was CME config)  to route calls to a specific DID,
hunt through lines and as a last resort dial outbound to a telco analog
line with a mailbox to leave a message (important). 

We did SRST testing for all of our locations locations about 2 months
ago and this particular location did not function at all with this "CME"
config.  I have since converted them to SRST, had an outage and their
calls did work. 

The business is claiming that this worked at one time during SRST but I
am skeptical.   I am thinking that the previous admin told him it was
configured but there was no real testing done.  Can anyone shed some
light on this.  I need to know: 

1) Can CME be used instead of SRST? 
2) Can I accomplish what they want via SRST? (see red above - I think I
can with the alias command but need to check) 

  Below is the full CME config if needed.
