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

[Brian Turnbow]

I tried with the prior version of patton software using a 4634 with sip and was unsuccessful. ( had the same problem)
Unfortunately I didn't have alot of time to dedicate to it as it was not a feature that was fundamental for the installation.
Also had problems with t.38 and cisco, fax passthru works well though.

If you get it working I'd love to hear about it ( t.38 as well for that matter)

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
