| 3 | 18 | dexter | h2. Introduction |
| 4 | |||
| 5 | 1 | msuraev | osmo-sip-connector translates between MNCC and SIP protocols. It does not handle RTP by itself but with the help of external SIP server it can be used for tests. |
| 6 | 2 | msuraev | |
| 7 | Sample configuration: |
||
| 8 | |||
| 9 | <pre> |
||
| 10 | app |
||
| 11 | mncc |
||
| 12 | socket-path /tmp/bsc_mncc |
||
| 13 | sip |
||
| 14 | local 10.9.10.105 5069 |
||
| 15 | remote 10.9.10.105 5060 |
||
| 16 | </pre> |
||
| 17 | |||
| 18 | Running osmo-sip-connector: |
||
| 19 | <pre> |
||
| 20 | osmo-sip-connector -c ~/.config/osmocom/osmo-sip-connector.cfg |
||
| 21 | </pre> |
||
| 22 | |||
| 23 | 3 | msuraev | Running NITB: |
| 24 | <pre> |
||
| 25 | ./src/osmo-nitb/osmo-nitb -c ~/.config/osmocom/open-bsc.cfg -l ~/.config/osmocom/hlr.sqlite3 -d DLMUX:DRTP -m |
||
| 26 | </pre> |
||
| 27 | |||
| 28 | 4 | msuraev | The configuration above assumes that SIP server is running on the same machine. Attached is example configuration file for Kamailio https://www.kamailio.org SIP server which can be used to route calls between mobile phones. It also handles 2 special numbers 500 (routed to sip:music@iptel.org) and 600 (routed to sip:echo@iptel.org): by dialing them you can use echo test or hear nice music from your mobile. |

| 30 | 7 | neels | *Note:* in attached kamailio.cfg, for 64bit systems, you may need to adjust |
| 31 | <pre> |
||
| 32 | mpath="/usr/lib/x86_64-linux-gnu/kamailio/modules/" |
||
| 33 | </pre> |
||
| 34 | |||
| 35 | 2 | msuraev | N. B: Those numbers are meant only as an example for quick tests - please consider running your own Asterisk instance if you expect more than couple of calls, do not abuse http://www.iptel.org/service |

| 38 | 18 | dexter | h2. Asterisk howto |
| 39 | 8 | dexter | |
| 40 | 20 | dexter | This howto was created and tested using Debian 8.7.1. It is assumed that there is already a working installation of osmo-nitb already exists. In the following steps we will show how to integrate an existing installation with asterisk using osmo-sip-connector. The following image illustrates how the network components wile be laid out: |

| 47 | 14 | dexter | "osmo-nitb" -> "osmo-sip-connector" [label = "mncc"]; |
| 48 | 15 | dexter | "osmo-sip-connector" -> "asterisk" [label = "sip"]; |
| 49 | 16 | dexter | "BTS" -> "asterisk" [label = "rtp"]; |
| 50 | 8 | dexter | } |
| 51 | }} |

| 53 | h3. Preparations |
||
| 54 | |||
| 55 | 24 | dexter | As we assume that we use an existing and working osmo-nitb configuration as a starting point most of the relevant dependencies are already installed. However, we still miss osmo-sip-connector and asterisk as a major components. |
| 56 | 23 | dexter | |
| 57 | 21 | dexter | h4. Install dependancies |
| 58 | 22 | dexter | |
| 59 | 21 | dexter | The extension we are about to make requires to install some additional packages. |
| 60 | <pre> |
||
| 61 | sudo apt-get install libsofia-sip-ua-glib-dev |
||
| 62 | sudo apt-get install asterisk |
||
| 63 | </pre> |
||
| 64 | |||
| 65 | h4. Install osmo-sip-connector |
||
| 66 | 22 | dexter | |
| 67 | 21 | dexter | The installation of osmo-sip-connector is as straight forward as you know it already from other osmocom projects: |
| 68 | <pre> |
||
| 69 | git clone git://git.osmocom.org/osmo-sip-connector.git |
||
| 70 | cd osmo-sip-connector/ |
||
| 71 | autoreconf -fi |
||
| 72 | ./configure |
||
| 73 | make |
||
| 74 | sudo make install |
||
| 75 | </pre> |
