Odd IP Status Station Response involving Encryption
Hello -
I wanted to pose this to the group and see if they have seen this behavior and/or have an answer as to why it is showing up this way.
We have a S8730 running CM 5.2.1 SP 02.1.016.4-19308.
While doing a status station command on a IP Phone, I noticed this oddity:
status station 96086 Page 8 of 10
VOICE STATISTICS

status station 9xxxx Page 9 of 10
SRC PORT TO DEST PORT TALKPATH
src port: S00060
S00060:TX:xxx.xxx.xxx.xxx:2796/g711u/20ms/1-srtp-aescm128-hmac80
01A0502:RX:yyy.yyy.yyy.yyy:3172/g711u/20ms/1-srtp-aescm128-hmac80:TX:tdm:a185
01A1314:RX:tdm:a185
As you can see from the above status station command, we have a call up, tied to a DS1 and from the Voice Statistics it shows Encryption is NONE.
But the next page (Talkpath) we see we are using the AESCM128-hmac80 encryption. So why is the Voice Statistics now showing this as none?
I am GUESSING because the Maintenance Command Document doesn't make reference to this type of encryption maybe CM doesn't know what to display there, but seems odd to me that on one page it doesn't know what it is but the other page shows it.
OR maybe because you can't encrypt over the DS1, but to me the Voice Statistics page is for IP only, so to me that theory doesn't make sense.
Anyone run into this before and/or have a logical answer?
Thanks -
James
