Re: [Serusers] Get RealTime Online Users status - sr-users

Looks you have SIP ALG enabled on your NAT, which breaks the call
transfer (no surprise, I haven't seen working SIP ALG yet).

Check OPTIONS request sent by SJphone and received by SER, check NOTIFY
sent by SJphone and received by SER.

Disable the SIP ALG and try again. If you can't disable it, change the
NAT box itself.

 Hi,

 unless you post the network capture and your config file (but make sure
 you don't disclose anything you want to keep secret) there is nobody who
 can help you. 

 The only answer is: your script is broken, except the answer 42, but I
 don't think your question was the ultimate question about life, universe
 etc. ;-)

 Michal

 P.S. If you haven't read "Hitchhikers guide to the universe" don't
panic
 and just forget the answer 42.

  Hi Jiri!

 I've captured and analyzed those SIP message dumps. I found that when
 Sjphone A sent a NOTIFY signal to the SER (after Sjphone A accepted the
 REFER), SER didn't pass the NOTIFY to the SPA942 to terminate the call
 between them.

 Therefore, Sjphone A unable to INVITE Sjphone B to bridge up the  connection.
  May I know what causes this?

 Thanks for your precious time and reply!

 Cheers,
 Roa Yu :)

  using
Sjphone A to SPA942, then use the SPA942 to transfer the call to
Sjphone B.

        SJPhone A --> SPA942 --> SJPhone B

After a short conversation with SJPhone B, then I press the 'xfer' button 
on
 the 2nd time so that both SJPhone A and SJPhone B
can talk to each other.
But the call couldn't be transferred to SJPhone B whereas when I used
Asterisk, it's able to do so.

I've tried to disable the Digest-qop but it still couldn't perform the
transfer properly. What other settings that I need to configure on SER?  
 I'm afraid you've gotta analyze SIP message dumps to figure out what's 
gone
  wrong. -jiri

yes.
well for some SPAs you may need to disable digest-qop since they have a  bug.
