[cisco-voip] Clear Channel Codec between Cisco GW and Patton Smartnode

[rschuknecht at gmx.de]

Hi,

i have to establish an H.323 connection between an Cisco 3745 and an Patton
Smartnode 1200 with clear-channel codec to support ISDN-Data over VoIP.

 PC with ISDN-Card---S0/PattonGW----H.323----3745/E1----PSTN

Software versions:
Cisco:  SPServices 12.4(5a)
Patton SN1200: R3.20 2006-03-30 H323

The call establishment is sucessfull but i am not able pass any Data over
ISDN. Does anyone got this working?
Any help is welcome.

Regards,
Robert
