Hi,
I have tested Jabber with 9971 IP Phone and it work properly.
However, when I tested Jabber with linphone (http://www.linphone.org/), it failed when call was received.
The problem is codec. Because I enabled only iLBC, GSM and G722 codecs on my linphone but when I enable PCMU or PCMA codec, it works.
The question is is it possible to use G722 codec with Jabber? If so, please clarify how to config.
FYI, I had registered linphone with CUCM8.6.2.20000-2 as Third-party SIP Device (Advanced) and it can call my 9971 IP Phone and work properly.
And Please see Jabber call's log in attachment.
Thanks and Regards,
