Obsolete Pulse Transformer - Need replacement part!!

Hello all,
I'm currently working on some Cisco CP7906 phones, and a few of them won't boot up, and have this old Pulse Transformer failing (p/n: H2312NL).
But, putting that in the search engine yields nada.
I tried looking through the products on the Pulse website, but wasn't able to determine an equivalent.
What I do know is, it's and audio and signal transformer, XFMR DUAL POE.
I'm sure this is a long shot, but if anyone has any info on what the replacement part number may be, that would be lovely.
Oh, I did request some info from Pulse as well, but figured I'd try the trusty forum too, see if anyone knows.

Thanks!!

perhaps small TV horizontal driver transformers, being ferrite core type, could well work as pulse transformer upto atlest 20KHz.
