Hi,
Is it possible to manually give the MS a timeslot number to listen to after it has performed location update ?
Yes, you can. See the L1CTL_DM_EST_REQ in L1CTL protocol implementation. But keep in mind, that as soon as you switch your phone to another timeslot (other than BCCH), you will be unable to 'hear' Paging Requests.
Regarding to your initial question, you was asked to provide the traffic dumps, but there are still nothing. So, it's still difficult to understand, what's happening on your side :/
With best regards, Vadim Yanitskiy.
Hi, I have attached a .pcap file showing a location update and then an originated call.

As suspected CCCH-CONF is 6, so it uses other timeslots than 0 for paging and which time slots is used for your SIM depends on a formula and the IMSI, you can't just select it. Currently osmocom-bb only support timeslot 0, so you're out of luck there, you'll need to add support for it yourself if you want to use it.
Cheers,
Sylvain

If I intend to use only one phone (always same IMSI) on only one specific BTS I would be able to calculate the timeslot, in this case is it possible to have the value of the timeslot hardcoded as a start for testing since I’m still new to osmocombb and must read a lot of code before being able to adjust it for my needs.

Nope because there is still a need to use timeslot 0 for BCCH and there is no provision in the code at the moment to have a different timeslot for BCCH and PCH..

So does using two motorola phones useful?

Using two phones wouldn't bring you any closer to solving your issue. It is not about the amount of phones.
