MiTel 5000 IP PBX how to disable the encryption?

[xdzhao]

We have a MiTel 5000 IP PBX, Software version: Rel. 5.0 SP2. It work whit 5340 IP phone. I checked the signal packets are not encrypted. However one of our customer sent me a pcap file that shows the signal packets are encrypted. This customer also use the MiTel 500 IP PBX with 5340 IP phone. Is there any way to disable the encryption? Thank you very much!

The 5000 uses RTP to transport audio and it isn't sent in the clear for obvious reasons.    Generic SIP phone traffic is though, so your only option is to use old SIP firmware on that particular telephone set and join the set to the 5000 as a SIP phone, and lose a ton of functionality in the process.  You'll also need a category F license for each SIP phone you wish to add.

Short version, don't do this.  What are you trying to accomplish?

He is likely trying to do a Wireshark capture for something, this is common in the 3300 and it contains a system level option to enable/disable encryption on the fly for this purpose, other than that there is no real reason to disable the encryption.

I am not aware of a way to do this on the 5000.

Pre Mitel, I did a bit of wireshark troubleshooting and all I needed then was G.711 or G.729 decoders. There was no VoIP encryption at that point. I have not tried since Mitel endpoints were brought into the mix.

Thank you everybody!
We have a product for call recording. We monitor the signal packets and find out the info if there is a call come in/out. Then notify our customer start/stop recording. So the raw signal packets are every important for us. Our product can support many PBXs. For the MiTel3300 the signal packets are encrypted. We can’t support it. When MiTel5000 comes out, we tested and found that MiTel5000 signal packets are not encrypted. (Software version: Rel. 5.0 SP2) We made our products support it. Now we saw some of the MiTel5000 users have the encrypted signal packets. The RTP packets looks like not encrypted.
Can someone help us to change the MiTel5000PBX settings to disable the encryption feature on the PBX. Thank you very much!

xdzhao,

The issue here is that you are trying to circumvent the manufacturers "pay to integrate features", which is why they most likely set the encryption on there in the first place. All of the manufacturers that integrate with the 5000 utilize the System Open Architecture Interface [OAI], which requires that you pay them to be able to get the SDK and codes in order to do that.

Sorry,

Also just for further info you can turn off encryption on a 3300 in the system options.

Thanks. I will ask our products manager to contact MiTel.

Isn't this application what the secure recording connector was made for?
