PAP2T Remote-Party-ID: wrong interpretation

‎01-10-2012 12:41 PM - edited ‎03-21-2019 09:41 AM

My PAP2T works with YouMagic SIP Service (http://www.youmagic.com/index.php?lang=en)

It displays wrong Caller ID - it displays MY number (+7499709xxxx) not calling party number (+7916xxxxxxx)

Wiresharked INVITE request

All rest parameters are factory default

SIP Remote-Party-ID is No. T tried turn ty Yes - no changes.

Initially I tried firmware version 5.1.6(ls) (factory default) and later I tried firmware versions pap2t-03-01-10-LS-c.bin, pap2t-3-1-15-LS.bin, pap2t-3-1-16-LS.bin, pap2t-5-1-1-LS.bin, pap2t-5-1-3.bin - no changes

Anyone can explain this phenomena? Thank you.

A SIP user agent should use one of these fields to get the calling number (in theory in this order):

P-Preferred-Identity/P-Asserted-Identity

Remote-Party-ID

From Header

Your issue sounds like a bug.

To be sure you should add the PAP log.

Can you post the log of incoming calls?

Regards.

Hi, I investigate the problem with my SPA2102. I replicated your call with the attached INVITE and I confirm the issue.

After that, I removed the second Remote-Party-ID from the INVITE:

Remote-Party-ID: <7499709XXXX>;party=called;npi=1;ton=0

In this case the Calling number displayed is correct.

The new INVITE is:

INVITE sip:7499709xxxx@a.b.c.d:34148;rinstance=2e75e33eb1045b0e;transport=udp SIP/2.0

I tested a second case. Remote-Party-ID swapped. The new INVITE is:

INVITE sip:7499709xxxx@a.b.c.d:34148;rinstance=2e75e33eb1045b0e;transport=udp SIP/2.0

Also in this case the Calling number displyed is correct.

CONCLUSION:

The Linksys SIP stack uses the last Remote-Party-ID to get the CLI even if it specifies the party=called option.

This is a BUG present also on SPA2102.

Please open a case with the support.

Regards.

I assume that it's bug too. However here is two bugs.

The first bug is Linksys SIP stack uses the last Remote-Party-ID to get the CLI even if it specifies the party=called.

And the second bug is that PAP2T uses Remote-Party-ID header even if  "SIP Remote-Party-ID" parameter value set to No. (As discribed in Cisco Small Business ATA Administration Guide "SIP Remote-Party-ID" parameter "To use the Remote-Party-ID header instead of the From header, select yes. Otherwise, select no". We can see that ndependently of "SIP Remote-Party-ID" parameter PAP2T uses Remote-Party-ID header nor From header.)

I just tested SPA922. The fist bug take place. Here is no second bug. because instead SIP Remote-Party-ID" parameter "Caller ID Header" introduced in FW version 6+ and setting the parameter value "FROM" works well - phone displays Caller ID of FROM field of INVITE.

Thank you Daniele. Of course I did it at January'12. They say that they will read the post, then they will think about, and then they will answer me. However hire is no sound from them up to now. Probably reading or thinking in progress.
