[SR-Users] Cisco 79XX Series Phones and TLS integration with kamailio

[John Murray]

Jon hi,

 

Which software version/image do you find works best for this?

We found some later versions to have introduced more problems.

 

Regards

 

John

Hi Mark,

 

Sure of course, they are some what painful to get working due to their
asymmetric NAT behaviour.

 

What handset models are you working with, and what firewall devices do you
have on site, as I have them working with a Cisco ASA on the network edge.

 

Then I can give you some more details on at least them trying to register to
kamailio.

 

Thanks

 

Jon

Hi Jon

 

It sounds like you're a few steps in front of me.  I'm just starting to try
and get a working set of config files etc for provisioning to the phones.
Which at the moment is going through the motions of registering but not
actually sending anything.

 

Would you mind sharing your experiences so far?

 

Thanks

 

Mark

Hi All,

 

As you guys might remember I have been doing alot of work with these legacy
handsets recently, in particular the Cisco IP phones 7945G and 7965G.

 

They work well now with kamailio, using UDP or TCP as the transport
protocol.

 

I am now looking to implement SIP over TLS with them, and wondered if anyone
had completed the same, as it appears they were designed very much to
support SIP over TLS and SRTP but with Cisco call manager and not other SIP
devices.

 

I am trying to understand if its possible to integrate with kamailio, as
from Cisco documentation it appears a CTL file (client trust list) is
required which seems to be generated by cisco software, and the handset
needs it before it will try to initiate a SIP connection over TLS.

 

I have implemented TLS /SRTP with Cisco SPA's, Bria etc on kamailio fine, so
its more a question around the handset and if anyone has achieved this.

 

Thanks

 

Jon
