i tried with command

where /etc/sip-proxy/certs/sip-proxy/key.pem is the same file as
specified as tls module private key:

modparam("tls", "private_key", "/etc/sip-proxy/certs/sip-proxy/key.pem")

nothing comes to console.  i must have misunderstood the command.  i
also tried with -i eth0, but it didn't help.

i was able to figure out how do to it using wireshark.  one needs to go
to Preferences/Protocols/SSL and there add to RSA keys list:

<ip-of-sip-proxy>,5061,sip,/etc/certs/sip.mydomain.com/key.pem

then in Options specify 'port 5061'.  after that, new ssl connections
will be shown in clear.

i don't know why ssldump didn't work with the same key.pem file.

Just a note: this only works when non-DH ciphers are used. I added a wiki page:
