FS, SS7 and Dialogic IMG2020 in the UK
Hi all, We're looking to get a pair of Dialogic IMG2020 for some BT Ofcom regulated SS7 interconnects: http://www.dialogic.com/en/products/gateways/img/img2020.aspx Any issues known with FS behind these? Thanks, Gavin. -- http://www.surevoip.co.uk
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 Alex, I'm on my phone but Mike/Brian can probably elaborate. From what I recall it was somewhat sporadic but reproducible. On Saturday, May 2, 2015, Alex Balashov <abalashov@evaristesys.com> wrote:

Hi, I've had to use FS in a SIP-I context. The first issue was that FS truncates SIP messages once it finds 0x00... The dirty workaround was creating a binary to hex representation converter module in Kamailio. We also had some problems with multipart invites/responses. Especially multipart responses with SDP in it as well as ISUP. Here are the bugs : https://freeswitch.org/jira/browse/FS-6875 https://freeswitch.org/jira/browse/FS-6877 On Sat, May 2, 2015 at 11:00 PM, Kristian Kielhofner <kris@kriskinc.com> wrote:

Hi, we have just installed a freeswitch for SIP interconnection with 100rel enabled. Currently it is running fine, but you have mentioned, that there is a bug. Should I be worried about segfaulting or any issues? btw, we use also dialogic with FS behind it with no 100 rel enabled and it is working fine. Its an IMG 1010 Thanks, Thomas On 03.05.2015 00:00, Kristian Kielhofner wrote:

Same here, FS boxes receiving and sending SIP trafic from/to IMG1010 gateways. It has been running for two years without any issue. Florent 2015-05-04 10:35 GMT+02:00 Tomáš Boros <boros@vmtele.com>:

Just found this! Thanks. We're going into testing this month. That's how long the BT process takes. On Saturday, 2 May 2015, Kristian Kielhofner <kris@kriskinc.com> wrote:
