T37 onRamp on CUBE ?

Combination View Flat View Tree View
Threads [ Previous | Next ]
On CUBE, is it possible to accept a T38 fax on inbound SIP leg and send to MMOIP T37 store-and-forward to ESMTP server with PVDM2-64, but no TDM card?

I wish to port a hybrid TCL/vXML application from as5400hpx to CUBE (IPIPGW) on as5350xm (with PVDM2-64).  The existing application has T37 onramp functionality using same number for voice/fax (fax detection).  The onRamp fax works when the inbound leg is either TDM or SIP.

The CUBE does have one PVDM2-64, I will add more after initial development and testing.
The CUBE will NOT have any TDM cards, SIP only.

My initial tests have NOT been successful.  I will do more testing and post more details if someone can confirm this is even possible.

T37 fax only works on TDM gateway. The input needs to come from T30 TDM interface. Don't think will work if the input is T38.

Thanks,

Can it DETECT fax without using DSP/TDM ?
 
If so, can I SIP redirect the incoming leg to a TDM loop?
 
Also, you say "Don't think will work",  do you KNOW it won't work?

DSP is needed for fax tone.
 
Thanks,
 
Yawming

Right, let me ask again.


Is it possible to accept a T38 fax with DSP and without TDM card?

If not, can I detect the T38 fax on non-TDM IPIPGW and if fax detected, then redirect the incoming SIP leg to a fax server ?
 
If none of the above will work, can you please point me in the right direction using IPIPGW with some calls needing fax detection?
