Cisco 2811 TLS Handshake problem

Hi,

I am trying to test TLS functionality using Cisco 2811 as voice gateway.

My set up is like

A <-------->Cisco 2811 <----------->B(SIP softphone)

where A is TLS enabled SIP peer.

B is a normal SIP Phone.

Call from B to A is successful.

Call from A to B is unsuccessful.

A side waits for 5 seconds after sending Client Hello and then disconnects.

It seems Cisco is not responding to Handshake messages.

I have tried to debug using debug crypto pki commands but nothing coming in the debug.

Please find the existing config details of the Cisco in the file attached,

Mohit

Hi ,

Just to add ...i found one info in one of the documents

Enabling TLS Listener Port

Use this command in “sip-ua” mode in order to enable the TLS port on TCP 5061 to listen:transport tcp tls

But on adding this command in sip-ua mode ,i still cannot see this command in the running config


    Is it a bug? how can i enable transport tcp tls  ?

    Here is the document i read for reference

    http://www.cisco.com/en/US/products/sw/voicesw/ps5640/products_configuration_example09186a008092acef.shtml

    Thanks

    Mohit
