Refreshing/Resetting UICC (SysmoISIM-SJA2)
by bryan coxwell 06 Jan '22

06 Jan '22

Hi all, I have a SysmoISIM-SJA2 which I believe doesn't have a CAT application and doesn't support the SUSPEND APDU (per the manual). Given that, is there any way to reset/refresh the card through APDU commands (or through any other means)? Would something along the lines of deactivating and then reactivating the USIM application work? Thanks, Bryan

Wanted: pcap file of Iu interface of 3G circuit-switched video call
by Harald Welte 14 Dec '21

14 Dec '21

Hi, I'm wondering if anyone has a pcap file containing an Iu (or Iuh) interface protocol trace of a classic 3G circuit-switched video call around? I would be curious particularly in the user plane side, i.e. showing the RTP with IuUP for video calls. But I presume the RAB assignments are also going to be interesting... I know Dieter used to play with 3G CS video with one of his handset testers. Hoewver, I doubt that device would have any Iu interface internally, so this will unlikely provide any help here :/ Thanks in advance, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

OSMO-MSC External MNCC integration with FeeSwitch
by Justin 07 Dec '21

07 Dec '21

Hi Osmocom, I'm trying to integrate the FreeSwitch as my external MNCC in my test lab using split stack. Currently, I'm getting an error message on FreeSwitch SIP/2.0 400 Missing Contact Header. I'm little bit confused with the error and I don't know where to troubleshoot this. I've attached my osmo configurations and pcap trace for your reference. Hoping for your reply. Thank you. Regards, Justin Mark Repollo
