You will find some differences, SETUP are different (one is in overlapping and the other in block mode). Then, can some explain this behavior. Normal call with SETUP with sending complete, works OK.
Any ideas?. Thanks in advance. Regards.

If you forward using trunk group seazure instead of ARS does it work?

In feature design external diversion mode parameter is joining?

[tincho.rn]

Hi tot3nkopf, it seems that in OXO if you use trunk group seizure or ARS, during forwarding the system makes a SETUP with Sending Complete. I would like to test forwarding without sending complete, but I don't know how. However my customer wants to use ARS always.
I will check External Diversion mode.
Thanks. Regards.

[tincho.rn]

Hi. External Diversion mode is in joining. any other idea?. regards.
