49.5. Connecting Abilis and a SIP server

49.5. Connecting Abilis and a SIP server
	Chapter 49. SIP - Session Initiation Protocol

This section contains instructions for a correct set-up of Abilis CPX and SIP server interconnection.

49.5.1. Activation of the CTISIP resource

For the activation of the CTISIP resource refer to Section 49.1.4, “Activating the CTISIP resource”.

The basic parameters to configure are:

ACT: to activate the resource.
sesnum: to define the amount of simultaneous connections.

SRCADD: source IP address for outgoing connections [R-ID: the source IP address of the outgoing datagrams will be set to the current RouterID value; OUT-IP: the source IP address of the outgoing datagrams will be set on the base of the output IP interface; 1-126.x.x.x, 128-223.x.x.x: the source IP address of the outgoing datagrams will be set to the selected value; IP-nnn: use the current IPADD of the specified IP resource].

	Tip
	If Abilis has only one IP resource (and only one IP address), you can use the default value; otherwise if Abilis has more IP resources and more IP addresses the suggested configuration is `OUT-IP`.

DOMAIN: if Abilis has clients in the public side you can also specify a FQDN.

49.5.2. Example: Abilis and a SIP server registered in Abilis domain (SIP-TYPE:LOCAL-PEER)

In this case the server is a “normal” user like a soft phone, but the SIP-TYPE is LOCAL-PEER.

	Note
	`LOCAL-PEER` handling is similar to `PHONE` but it allows calling/called number to pass unchanged.

In the figure there are the following elements:

SIP server has dynamic IP;
Abilis has only one SIP user;
Abilis user is “test” with password “secret”;
Tip
Interesting chapters:
Section 49.1.3, “CTISIP INVITE messages”;
Section 49.1.2, “CTISIP Registration”;
Section 72.5, “How to configure a multicast group of SIP phones”.

Now you have to create a SIP user representing the user that is a client of the Abilis.

[14:49:07] ABILIS_CPX:a user:test pwd:secret sip:yes

COMMAND EXECUTED

[14:49:07] ABILIS_CPX:s user:test sip-type:local-peer sip-number:* sip-host:dynamic

COMMAND EXECUTED

	Note
	The SIP server isn't required to be only on the local network.

You can show the result in this way:

49.5.3. Example: Server and Abilis registered in Server remote domain (SIP-TYPE:SERVER)

In the figure there are the following elements:

Abilis is a user of SIP proxy domain “voip.it”;
“voip.it” has s static IP address: 88.88.88.88;
Abilis has a static IP address;
Abilis has only one SIP user;
Abilis user is “voipclient” with password “swordfish”.
SIP server provides advanced services like IVR and voice mail, let's say that 10 sessions are needed.

	Note
	The `SIP-CG-NUM` parameter is set to "`*`" to pass calling number transparently, because by default, this parameter is `AUTO` (enforces caller id information element equal to SIP-NUMBER).

	`REMOTE-PEER` handling is similar to `SERVER` but it allows calling/called number to pass unchanged.

49.5.5. CTI Routings configuration

Some routings in the CTIR table must be added in order to route the calls to and from the CTISIP resource.

49.5.5.1. Any coder, transcoding disallowed

Purpose of configuration: calls arriving from ISDN/POTS/GSM/CLUSTER are routed to SIP users, and calls arriving from SIP users are first sent to cluster test; in case of failure (NEXT:LIMITED) it's attempted on ISDN/POTS/GSM group G1.

In this situation any coder with maximal speed 6400 (the default for SP parameter) is allowed, but transcoding is disallowed. This means that the same coder must be used by the SIP proxy and Abilis.

	Note
	The routes `PR`:`0` and `PR`:`1` may be unified into one: *a ctir pr:0 poi: sr:* out:sip cdi:* descr:From_ISDN/POTS/GSM/Cluster_to_SIP**

	Note
	The `POI`:`` in CTIR routings identifies all CTIP ports: ISDN, POTS, VPOTS, CELL; and SR: identifies all clusters. Refer to Table 46.2, “Special characters and values available in CTI routing table” to know more about special characters and values available in CTI routing.

	Tip
	To allow G.729A you have to set `SP`:`8000` in every routing.

49.5.5.2. Only G.711 on SIP proxy, any coder on Cluster, transcoding allowed

Purpose of example: calls arriving from ISDN/POTS/GSM/CLUSTER are routed to SIP users, and calls arriving from SIP users are first sent to cluster test; in case of failure (NEXT:LIMITED) it's attempted on ISDN/POTS/GSM group G1.

In this situation only G.711 A-law or u-law can be used by SIP proxy and Abilis. Since transcoding is enabled by CODERSOUT <> * the CTI routings will negotiate for the “C” side any coder with maximum speed up 6400 bps.

	Tip
	To allow G.729A you have to set `SP`:`8000` in `PR`:`1` and `SPOUT`:`8000` in `PR`:`2`.

49.5.5.2.1. Transcoding optimization

When the Abilis-SIP proxy interconnection occurs via local LAN, (i.e. With high speed, minimal delays, minimal jitter), optimizing the transcoding can be done so that the SIP proxy side uses minimal jitter, minimal delays.

This is obtained by properly setting DJ, MJ, DJOUT, MJOUT.

COMMAND EXECUTED

[18:15:29] ABILIS_CPX:s ctir pr:2 dj:0 mj:80 djout:sys mjout:sys

COMMAND EXECUTED

	Tip
	`DJ` and `MJ` in `PR`:`1` as well as `DJOUT` and `MJOUT` in `PR`:`2` may assume other values appropriate for the WAN link or specifically required by calls matching the routing.

49.5.5.2.2. Fax

When transcoding takes place in CTI routing table, with G.711 toward the SIP proxy, something interesting happens: on the WAN FAX relay can be used! The Abilis can exchange FAX with following characteristics:

UIse G.711, 64 kbps plus IP overhead on the Abilis-SIP proxy interconnection;
Use G3 Fax relay, 2400/4800/9600/14400 kbps plus IP overhead on the WAN link.

Set FMRELAY:NO in the desired routing to disable fax relay:

The match for CTIR Routing in this example is SDO (The SIP user "voipclient") but not CDO (SIP number).

	Note
	If SDO does not match any SIP user then it uses the matching with CDO.

49.5.6. Last Calling Service for a SIP user

Assuming to have a SIP user (voipclient), let's configure the Last Calling Service so that a call received by the SIP server is routed to the last number which called the calling number.

	Warning
	Last Calling number Service requires a separate licence.

Suppose to have this situation:

CTIP 149 (for example number 49) makes a call to a phone (number 3201234567);
The call is routed through the SIP user "voipclient" (which corresponds to a number 0671061045);
The LCS saves calling and called numbers in the LCS table;
A call is received by SIP user "voipclient": the called number is 0671061045, the calling number is 3201234567;
The call is automatically routed toward CTIP 149 (number 49).

Suppose we have a SIP user "voipclient" with the following configuration:

	Important
	For routes towards SIP user is necessary to set the `LCS` parameter to `YES`, to activate the Last Calling Service. Another important parameter of CTIR routing is the LCST: Last Calling number Service records Timeout.The value `Sys` means the default value and will be the one setup by the CTISYS resource.

	Warning
	Changes made on the CTI routing table aren't immediately active. To activate them, execute the initialization command init ctir.

Type the following command to show the LCST entries.
