As Henning already answered, yes. But if you are security-consious it would 
from a SIP security standpoint require that their side present a client cert 
that you can verify so you are really sending calls to the right provider.

Hello,

for a start - did you already tried this parameter: 
http://www.kamailio.org/wiki/cookbooks/5.5.x/core#tcp_reuse_port

Then have a look for example to this discussion:

Cheers,

Subject: [SR-Users] Re-using an existing TLS connection

Hello,

My problem: our provider opens a TLS connection to us. They want us to use this 
channel for outgoing calls, instead of opening a new SIP connection to their 
server.

Is there a way to teach Kamailio to do that?
