Good day to you,again.
I have one more skinny issue:
I would like to make a group call to skinny phones and sip phones.So because of group_call does not work in case of skinny phones, i've add this to dialplan:

<extension name="Uginfo_groupcall">
<condition field="destination_number" expression="^11100$">
<action application="bridge" data="${group_call(Uginfo@${domain_name}+F)},skinny/internal/11000,skinny/internal/11006,skinny/internal/11004,skinny/internal/11003"/>
</condition>
</extension>

but when i answer the call on the 11006(cisco 7985),i have this in debug

2014-11-13 11:43:44.964830 [DEBUG] switch_core_session.c:1614 Session 146 (SKINNY/internal/11006) Locked, Waiting on external entities
2014-11-13 11:43:45.084825 [DEBUG] skinny_server.c:2453 [SEP0050600361BC:1 @ 10.4.33.12:23271] Received OpenReceiveChannelAckMessage (type=22,length=24).
2014-11-13 11:43:45.084825 [WARNING] skinny_server.c:1945 [SEP0050600361BC:1 @ 10.4.33.12:23271] Unable to find session for call id=84.

Could you help, please?
Thank you for your time,
Best regards
