Configuring call-manager-fallback error

[Kudur MohanRaj]

CUCM: 9.1

Phones work well registered to CUCM.

GW 2911 with IOS 15.2(4)M

configured call-manager-fallback

call-manager-fallback

secondary-dialtone 9

max-conferences 8 gain -6

transfer-system full-consult

timeouts interdigit 6

ip source-address 192.168.54.1 port 2000 strict-match

max-ephones 60

max-dn 90 dual-line preference 5

transfer-pattern .T

keepalive 10

time-zone 39

time-format 24

Problem definition:

When phones are in SRST, they register with the default gateway showing system message but no dn's.

thankyou in advance, please help.

Try adding "max-ephones XX" where XX is the number of phones you want to register.

Edit: i didnt look closely enough, you already have that. DOH!

Hi Kudur,

    Looking at the config you have provided I would begin by removing the "preference 5" portion of the max-dn line of config.  It looks like there are no specific alias matches that would need a higher preference than the max-dn line.

Thanks,
Tony

Hi Tonyperla,

I have removed the preference 5, even now it shows the same behaviour.

now it is :  "max-dn 90 dual-line"

[tonyperla]

What firmware are the phone(s) in question running?  Can you also get the phone to go back into SRST and from your gateway run "show ephone registered" and supply the output?  Thanks. 

Thanks,
Tony

Hi,

Thank you all and thanks for your inputs.

I configured CME SRST, which is operational.

Hi Mohanraj,

Glad that by CME SRST your problem is fixed.

But if it's possible for you to test with "call-manager-fallback" SRST, then please check below things:-

1). Check the SRST version

2). Check the Phone firmware supported for that SRST version.

It seems that there is an issue with Phone firware for the SRST version you are using.
