[cisco-voip] SRTP and TCL Interaction

[ROZA, Ariel]

Hi, people! I need help.

 

I am setting up call  encryption for a network, and I am having issues with a gateway.

 

I have an H323 gateways connected to the PSTN through an E1 interface.

The outgoing calls go through a TCL script that triggers a billing application.

 

When I set up the gateway to use SRTP, I use the following commands.

 

!

voice service voip

  srtp fallback

!

 

>From there, when I make a call to the PSTN, the SRTP leg of the call is not encrypted whenever the call goes through the TCL dial-peer.

If I route the calls to the PSTN through an alternate dial-peer that does not trigger the TCL script, the call is encrypted correctly.

 

Is there any known interactions between SRTP and TCLs that I am not aware of?

 

I can´t find any reference.

 

Thanks,

 

Ariel
