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,
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
