Hi,

We have set up a Server dition with remote phones, in front of the Server i have a Ingate sbc.
Actually calling from one remote phone to another works 2 way ( direct media disabled)
incoming call /outgoing call from/to sip to/from remote phoen gave me a oneway speach. (can't hear nothing on the remote phone)

In the ingate i've natted the rtp port range set n the /system/lan/port number range ( NAT) to the ipo.
But if i'm right the setting define the rtp range for H323 remote phone and SIP.
In the ingate sbc, i've to set the sip rtp range, but when i set it up it sais that the range is already used ( in the nat) .
If i disable the range in the nat i have no voice between the 2 remote phones :s

Could you confirm that the setting in the /system/lan/port number range ( NAT) is where i can set the range for the siptrunk.
Is it another way to use another range for sip ?

Thx

Port Number Range (NAT)
These settings are available when either H.323 Remote Extn Enable, SIP Trunks Enable, or SIP Remote Extn Enable is set to On.

This option is not supported if the Firewall/NAT Type (System | LAN1 | Network Topology) is set to Symmetric Firewall or Open Internet.

i read that in the doc too.
My question is how can i set a different range for the sip and for the H323 ?

Well, you can't... as said Remote Extensions and SIP trunks will use those ports as long as Firewall/NAT Type isn't set to the specified.

But in Ingate the SIP RTP range shouldn't need to match the IP Office RTP range.
Since it will make a separate connection between Ingate <-> Public and Ingate <-> Internal it just specifies which RTP ports it should listen to, it has nothing to do with the settings in IP Office.

thx for your answers, Ingate needed "semi transparent udp port forwarding " ...
