No reply from IBM WAS

[shijuwei@gmail.com]

I configured Express Talk base to use the SIP proxy in IBM WAS as the outbound proxy. But there's no reply from the server.

 

Default Line Setting:

Full 'Friendly' Display Name: Justin

Server (SIP Proxy or Virtual PBX): 9.186.50.138:5060

SIP Number (or User Number): justin

 

Here's the log of Network Setup Wizard:

09:55:40 Sip Port 5060 (UDP) opened OK

09:55:40 Local network IP is: 9.186.50.95

09:55:40 This computer connects to Internet directly

09:55:40 External IP is: 9.186.50.95

09:55:40 SIP Network Tool finished

 

Here's the log of call initiating:

09:55:56 Restarting so settings take effect.

10:04:09 Error call attempt timed-out.

10:04:09 The server is not replying.

10:04:09 Call has disconnected

I configure X-Lite to do the same task, it works well.

I used Ethereal to capture SIP/UDP packets and found that there's no SIP request from the host of Express Talk arrives.

 

Do not I configure the phone right?

I have fixed the problem. It possibly caused by my firewall.

 

BTW, it seems that WAS SIP proxy will route a INIVITE from X-Lite UA to Express Talk Basic (PPC Edition) via TCP. But the Express Talk in Mobile Device only opens the UDP 5070 listening port. I do not know whether Express Talk PPC Edition can work with TCP. Currently I can't initiate call via X-Lite --> WAS --> Express Talk (PPC). But I can successfully initiate calls via Express Talk (PPC) --> WAS --> X-Lite and Express Talk (PPC) --> WAS --> Express Talk (PPC).
