One-X Communicator R6.1 Call Session Error

[davis124]

Hello All -

Running into a wierd issue with the latest One-X Communicator R6.1, we are installing this as a test and it has been working great until we turned on Media Encryption on the IP-Codec set used for One-X Communicator.

As soon as we turn Media Encryption on (It doesn't matter if it's AES, AEA, or the SRTP types) One-X Communicator will then fail on making outbound calls with a Call Session Error. I know One-X Communicator is suppose to support SRTP but for some reason it's not working correctly or I am missing something.

Has anyone else had this type of problem?

Thanks,

James

Below are the steps required to get SRTP working on 1XC 6.1 :

Make changes on CM for SRTP (server side changes)

1) Ensure Media Encryption Over IP as Y on page 4 , using command change system-parameters customer-options
2) SDP Capability Negotiation for SRTP as y on page 19 , using command change system-parameters features
3) On CM , Media Encryption set as
1: 1-srtp-aescm128-hmac80
2: 2-srtp-aescm128-hmac32 using change ip-codec-set 1 command , refer attachments

1XC Clients side changes

-Hard phone 46xx settings file as well as clients config file should also updated /modified for SRTP


Useful for 1XC :

<parameter>
<name>MediaEncryptionParameters</name>
<value>1,2</value>
</parameter>


46xx settings file-(For desk phone mode)

##
## Media Encryption Support
## Specifies media encryption (SRTP) options supported by
## phone. Up to 2 options may be selected. Values are in
## comma-separated list. Options should match those
## specified in CM IP-codec-set form.
## 1 = aescm128-hmac80
## 2 = aescm128-hmac32
## 3 = aescm128-hmac80-unauth
## 4 = aescm128-hmac32-unauth
## 5 = aescm128-hmac80-unenc
## 6 = aescm128-hmac32-unenc
## 7 = aescm128-hmac80-unenc-unauth
## 8 = aescm128-hmac32-unenc-unauth
## 9 = none (default)
SET MEDIAENCRYPTION "1,2"
##

Please note that if SRTP is enabled , other non SRTP endpoint calls will be failed.
