SRTP, H323 VGW to CUCM encryption

[CHRISTIAN END]

Hello,

has anyone some good documentation (with examples) about encryption of conversation between phone, cucm and VGW (H323)?

I only found documentation about MGCP for signaling.

EDIT:

The phone encryption is clear. But the leg between CUCM and VGW.

Thanks

Christian

Hi Christian,

Please check the following section of the cucm security guide

OK, as i understand correct

1. I have to enable SRTP on CUCM.

2. I have to configure IP SEC on CUCM

3. Configure IP SEC on H323 VGW

(Is there an example Config for H323 VGW with IPSEC and SRTP?)
