[cisco-voip] insufficient bandwidth on Cisco ATA 188 with GnuGK

[vladimir botka]

Hi guys,

thanks to all who replied. The problem was solved by "Enable h245 
tunneling" on Cisco ATA. By default the bit 1 in parameter ConnectMode 
is 0 (disable h245 tunneling). So, when using Cisco ATA on internal 
network behind NAT&FW registred with GnuGK in Routedmode

[RoutedMode]
GKRouted=1
H245Routed=0
SupportNATedEndpoints=1

Cisco ATA is not able to negotiate PSTN connection parameters unless 
h245 tunneling is enabled. If you got similar problem try:

ConnectMode:0x00060402
instead of default
ConnectMode:0x00060400

Cheers,

Vladimir
