Cisco 3825 Voice Gateway Losing Configuration After Recovering From SRST

1hohs

Hi all,

I've notice this issue happening when the VG router recovers from SRST thus downloading the configuration from the Cisco CallManager. I'm just wondering is the a way to set the Call Manager to have the settings below. Thank in advance.

---- Current / Initial config ----

controller E1 0/0/1

framing NO-CRC4

pri-group timeslots 1-16 service mgcp <<<<<<<<<< We had to split the timeslots as the router doesn't have enough DSP ports

!

!

controller E1 0/1/0

framing NO-CRC4

clock source internal

pri-group timeslots 16-31 service mgcp

!

!

interface Serial0/0/1:15

no ip address

encapsulation hdlc

isdn switch-type primary-net5

isdn incoming-voice voice

isdn bind-l3 ccm-manager

no cdp enable

!

interface Serial0/1/0:15

no ip address

encapsulation hdlc

no logging event link-status

isdn switch-type primary-qsig

isdn protocol-emulate network

isdn incoming-voice voice

isdn bind-l3 ccm-manager

no cdp enable

-----------------------------------------

---- After recovering from SRST & configs downloaded from CCM ----

controller E1 0/0/1

framing NO-CRC4

!

controller E1 0/1/0

Appears that is a bug.

IOS used? can you upgrade and try again?

Currently running IOS 12.4(6)T6. I don't think it's a bug but more of the Call Manager settings as the router will download a config once it has established a ccm connection. Hope this helps
