VG224 in MGCP can be helped by GW in SRST ?

Hello everybody,

To have the VG224 operational in SRST, i configure it in SCCP on the CUCM.

If i use MGCP to configure VG224, can i have the voice gateway registered on the GW in SRST ?

Thanks,

Matthieu

Hello Matthieu,

I can think of 3 ways having srst with vg224 (3 options):

1.Changing the protocol of the VG224 to SCCP (easiest way to do it) as the following

example:

sccp local Loopback104

sccp ccm 10.104.20.101 identifier 101 version 4.1

sccp ccm 10.104.96.108 identifier 108 version 4.1

sccp ccm 10.104.96.104 identifier 104 version 4.1

sccp ccm 10.104.120.200 identifier 200 version 4.1

sccp

!

sccp ccm group 105

associate ccm 104 priority 1

associate ccm 108 priority 2

associate ccm 101 priority 3

associate ccm 200 priority 4

Where 10.104.120.200 is the SRST gateway. Add the srst reference in the device pool of the vg224

2.Applying the command the following commands to the MGCP gateway

ccm-manager fallback-mgcp

application

global

service alternate default

And configure dial-peers for H323 in case the router goes to SRST mode.

3.Convert the protocol to H323 and create 2 dial-peer one of them with preference 1 with

destination pattern , dial-peer two with preference 2 with

destination pattern

Hope this helps!

Thanks,

Karthik

Thanks Karthik,

I used only the first possibility, i will test the two others.

Thanks

Hi Karthik,

I just followed SCCP configuration, however i can not dial out between VG224 and SRST IP phone.

do i need to have dial-peer no SCCP ?

I could see VG224 successfully registerted to SRST VGW by command show ephone registration.
