Hi Alex,

  I'm on my phone but Mike/Brian can probably elaborate.

  From what I recall it was somewhat sporadic but reproducible.

Hi Gavin,

  The only potential things that jump out to me:

- Support for/requiring PRACK. This is often suggested/strongly recommended/required with SIP/SS7 interop. FS has a long standing bug with 100rel.

- Same for SIP-I/SIP-T. FreeSWITCH can pass these through with multipart but it can't currently parse or use them in any effective way. With that said I think I've seen people use LUA and other crazy stuff to parse specific data they absolutely needed...

  Other than that if these can be configured for fairly plain/straightforward SIP there shouldn't be any significant issues that I can see.

Hi all,

We're looking to get a pair of Dialogic IMG2020 for some BT Ofcom
regulated SS7 interconnects:

Any issues known with FS behind these?

Thanks,

Gavin.
