sipxCallRedirect and sipXCallTransfer

Hi,

Has anyone else encountered the following:

sipxTapi instance 1: registers Line 8000 <at> xxx.com
sipxTapi instance 2: registers Line 8001 <at> xxx.com
sipxTapi instance 3: registers Line 8002 <at> xxx.com

When a Call comes into 8000 it is redirected to 8001.
This call is then transferred to 8002.

The transfer fails using sipxTapi. Blind or Consult.
But it works ok if x-lite (eyeBeam) is plugged in for 8001.

Wireshark shows that the only major difference between doing this using x-lite or sipxTapi is in the contact header of the SIP REFER:

XLITE:Contact: <sip:8000 <at> xxx.com:5062>;LINEID=e27e3a08a40c;x-sipX-nonat
 SIPX:Contact: <sip:8001 <at> xxx.com:2228;rinstance=0cb1214fe2ba2461;transport=TCP;x-sipX-nonat>

Any help greatly appreciated

Mike

Re: sipxCallRedirect and sipXCallTransfer

Hi All,

I noticed an error in my example below: The Sipx and Xlite responses were the wrong way around. Should be:

SIPX :Contact: <sip:8000 <at> xxx.com:5062>;LINEID=e27e3a08a40c;x-sipX-nonat 
XLITE:Contact: <sip:8001 <at> xxx.com:2228;rinstance=0cb1214fe2ba2461;transport=TCP;x-sipX-nonat>

I am still stuck on this one. Has anybody encountered any problems using sipxCallRedirect()?

TIA

Mike
