3 beeps at call start after enabling SRTP on SPA502G

[kasper123]

I use asterisk (Elastix 2.4) and Cisco SPA502G phones.

After enabling SRTP on the phones I see that the traffic is encrypted but during every call there are 3 beeps at the beginning of the call. Probably this is to let me know that the call is encrypted but this is very irritating.

Is there a way to disable the beeps and keep SRTP enabled.

Second servis ;-)

... it seems you are hearing . Reconfigure it according your's wishes.

Thank you Dan. Yes that's the sound I'm hearing. Is there a way to setup a sound that I would just hear only once at the beginning?

I told you - you are hearing Secure_Call_Indication_Tone. It's on Voice/Regional tab of device's web configuration page.

You can reconfigure it to anything you wish - read aministrative guide for value syntax. For example

397@-19,507@-19;5(0/2/0,.2/.1/1,.1/2.1/2)

may fullfill your requirements.

One question which is maybe a bit related: I have the issue that I do not hear any call waiting tone during a SRTP call even though the values are set and the 2nd call is being notified on the display and on the MWI lamp. Do you have the same experience? I am running the latest SPA firmware and Asterisk 1.8.20.1.
