Hi all,
I'm having the folowing problem with sip calls:
When i try to call from cisco callmanager to a GSM sip gateway the callmanager never send the ack to a status 200:ok messague that is send from the gateway to the callmanager and since i dont have early-media configure the the sdp is never send from the callmanager to the gateway. The flow for the messages is the folowing :
CM to GSM-Gateway
INVITE->
<-TRYING
<-RINGING
<-SDP-STATUS:200 OK
<-SDP-STATUS:200 OK
<-SDP-STATUS:200 OK
<-REQUEST:BYE
STATUS:200OK ->
Since the ack to the status 200 OK is never send the call is never stablishes
Does any one have an ideia
Thanks

You need to be on 12.4(20)T or 12.4(11)XW7 or higher for the CP-500 phones to register.

I think it may be XW8. Trying to find original release, but cannot find the IOS required for these.
