osmo-sip-connector - Osmocom SIP connector
|
|
==========================================
|
|
|
|
This implements an interface between the MNCC (Mobile Network Call Control)
|
|
interface of OsmoMSC (and also previously OsmoNITB) and SIP.
|
|
|
|
Call identities can be either the MSISDN or the IMSI of the subscriber.
|
|
|
|
Requirements of Equipment
|
|
-------------------------
|
|
|
|
* DTMF need to be sent using SIP INFO messages. DTMF in RTP is not
|
|
supported.
|
|
* BTS+PBX and SIP connector+PBX must be in the same network (UDP must be
|
|
able to flow directly between these elements)
|
|
* No handover support.
|
|
* IP based BTS (e.g. Sysmocom sysmoBTS but no Siemens BS11)
|
|
* No emergency calls
|
|
|
|
Limitations
|
|
-----------
|
|
|
|
* PT of RTP needs to match the one used by the BTS. E.g. AMR needs to use
|
|
the same PT as the BTS. This is because rtp_payload2 is not yet supported
|
|
by the osmo-bts software.
|
|
|
|
* AMR SDP file doesn't include the mode-set params and allowed codec modes.
|
|
This needs to be configured in some way.
