Hi,
I do have on 2 different sites:
Site A :
Cisco phones 79xx and Softphone
2811 with CME7.1 IOS 12.4.24(T3)
Site B:
Cisco Phones 79xx and SIP third partie phones (DECT) using G711ulaw
1861 with CME7.1 IOS 15.0(1)M3
Calls between Site A (Softphone for testing over VPN IPsec Tunnel) and Site B from Cisco to Cisco works fine
Calls in site B from Cisco to SIP phones works fine
Calls from Site A Cisco softphone to SIP phones does call but I not hear ring the call on the softphone, it just stays off hook and notting happens more, until I hangup the call.
When I do retry the call, an error message is given on site B (Log)
%CALL_CONTROL-6-CALL_LOOP: The incoming call has a global identfier already present in the list of currently handled calls. It is being refused
First I was expecting a transcoding issue but I found on the forum that from phone to phone, there is no need to trancode.
Site A dialpeer

Hi,
As I did not get an answer her, I did open a TAC case.
Lot of work but now it works...
Solution 1 site SIP third party:
Definition from the voice in alaw/ulaw
Solution multisite SIP third party:
Changing also the trunk to the sites as alaw/ulaw or add txcoder to the SIP sites
