Hello,

maybe the new phones do STUN and or the ALG breaks somehow the signaling. You should send the ngrep output taken on sip server for such a call in order to be able to analyze what can happen:

ngrep -d any -qt -W byline port 5060

Cheers, Daniel

Hi guys,

we have a bunch of SIP phones behind a fire wall, with our kamalio server out on the internet. Most of them are the older SPA92x series, but we have some new SPA502g's.

We have no problems calling between 92x and 502's. How ever the 502's calling each other do not get voice path.

I have noticed that the phones REGISTER differently:

      AOR:: 5546@<our domain>
              Contact:: sip:5546@<OUR OFFICE IP>:1032 Q=
                      Expires:: 180
                      Callid:: 4754c4f9-c67e1018@10.0.41.29
                      Cseq:: 43112
                      User-agent:: Cisco/SPA502G-7.6.2a
                      State:: CS_DIRTY
                      Flags:: 0
                      Cflag:: 0
                      Socket:: udp:<OUR SR IP>:5060
                      Methods:: 6815


      AOR:: 5590@sip.skunkworks.net.au
              Contact:: sip:5590@10.0.41.14:5060 Q=
                      Expires:: 1154
                      Callid:: 24435738-224b06db@10.0.41.14
                      Cseq:: 8012
                      User-agent:: Linksys/SPA921-5.1.8
                      Received:: sip:<OUR OFFICE IP>:1026
                      State:: CS_SYNC
                      Flags:: 0
                      Cflag:: 64
                      Socket:: udp:<OUR SR IP>:5060
                      Methods:: 4767

The older 921 has its private IP in the contact, where as the newer 502 has the external IP of our office in the contact.

Our file wall is a Watchguard T-10 (latest updates etc) with the SIP-ALG running.

Any thoughts on where to start looking ?

Cheers,

Ben.

Hi Daniel,

I have attached the gzipped ngrep log I created. There are a number of calls between two of the phones in question, all with out audio working. The phones work fine when calling a different model, or when receiving/make external calls.

Ive had a look as I changed the ip address and domain, but really dont know what I am looking for.

Cheers,

Ben.
