I am working with a faxing system that is giving me more nightmares than I can even count... I am working with a software system that sends FoIP using T.38 and V.17 faxing. It does not support G711 fallback, and that has been giving us fits like you would not believe our upstream carrier. The specific issue lies in paths which do not support T.38 and are trying to do G711 fallback. I have a pair of 3825 router configured as UBE's in an HSRP configuration.
I am looking to mitigate some of these issues by implementing a couple of TDM PRI's (one to each device). These PRI's will be configured in an active/passive failover group from the carrier side uplinked into the existing 3825 UBE's. My question is on the conversion as I have never done this before. I know this will pull a DSP (or a couple) for each transcoding session, so I have 8 PVDM 64's I am going to throw in these routers. I still need to be able to support SIP in case of a PRI failure as both PRI's come in on the same channelized DS3. Has anyone had to do this before? Specifically with T.38. Had good luck with it or should I look towards the solution I planned for next year which was a pair of ASR1001 routers to act as SBC's and handle these functions. Thanks in Advance, Blake
