14.5.3.2.1. Configuration with ISDN Numbering Plan (recommended) 
Using ISDN International Format is the easiest and recommended way
for SIP numbering configuration. The format will then result in + being
prefixed before the numbers in SIP. Using + is also preferred format
for receiving numbers from any SIP Provider.
In AMO BFDAT a function block must be preset for HG 3550:
ADD-BFDAT:FCTBLK=3,FUNCTION=HG3550,BRDBCHL=BCHL60&BCHL120; CHANGE-BFDAT:CONFIG=CONT,FCTBLK=3,FUNCTION=HG3550,LINECNT=2,UNITS=3; CHANGE-BFDAT:CONFIG=OK,FCTBLK=3,ANSW=YES;
HG 3550 is configured with function ID 1 and the functional
block 3 described above:
ADD-BCSU:MTYPE=IPGW,LTG=1,LTU=1,SLOT=10,PARTNO="Q2324-X500",FCTID=1,LW VAR="0",FCTBLK=3,BCHL3550=60,ALARMNO=0;
The HG 3550 IP address is entered in the AMO CGWB. In
this case, it is an address from the WAN allocated by the service provider.
The DNS whose address is also entered here as DNSIPADR, is also in the
service provider area:
ADD-CGWB:LTU=1,SLOT=10,SMODE=NORMAL,IPADR=3.3.3.11, NETMASK=255.255.255.0,BI TRATE="AUTONEG",TRPRSIP=60,DNSIPADR=2.3.3.123;
In the AMO CGWB, LEGKDATA section, the number of gateways
is entered (GWNO):
CHANGE-CGWB:MTYPE=CGW,LTU=1,SLOT=10,TYPE=LEGKDATA,GWNO=1,REGEXTGK=NO;
In the AMO CGWB, external registration and digest authentication
remain deactivated:
CHANGE-CGWB:MTYPE=CGW,LTU=1,SLOT=10,TYPE=SIPTRERH,GWAUTREQ=NO; CHANGE-CGWB:MTYPE=CGW,LTU=1,SLOT=10,TYPE=SIPTRSSA,SIPREG=NO;
You can configure a bundle for the SIP carrier application:
ADD-BUEND:TGRP:=55,NAME="SIP CARRIER",NO=60;
The following COT/COP classes are recommended:
ADD-COT:COTNO=55,PAR=ANS&CEBC&BSHT&BLOC&LWNC&NLCR&TSCS&NOFT&NTON; ADD-COP:COPNO=55,TOLL=TA,TRK=TA; ADD-TDCSU:OPT=NEW,PEN=1-01-010-0,COTNO=55,COPNO=55,DPLN=0,VBZ=0, COS=1,LCOSV=1,LCOSD=1,CCT="SIP CARRIER ", DESTNO=0,PROTVAR="ECMAV2",SEG MENT=8,ATNTYP=CO,ISDNIP=00,ISDNNP=0,TRACOUNT=31,SATCOUNT=MANY,NNO=1-40- 155,ALARMNR=2,FIDX=1, COTX=55,FWDX=1,UUSCCX=16,UUSCCY=8,FNIDX=1, CLASSM RK=EC&G711&G729AOPT,TGRP=55,SRCHMODE=DSC,INS=Y,SECLEVEL=TRADITIO,DEV=HG3550 CO,BCHAN=1&&30,BCNEG=N,BCGR=1,LWPAR=0;
If more than 30 B channels are required, the set 1-1-10-1
can be identical.
A RICHT is required for the LCR:
ADD-RICHT:MODE=LRTENEW,LRTE=55,LSVC=ALL,TGRP=55,DNNO=1-40-155;
You also need an outdial rule:
ADD-LODR:ODR=56,CMD=ECHO,FIELD=4; ADD-LODR:ODR=56,CMD=ECHO,FIELD=5; ADD-LODR:ODR=56,CMD=ECHO,FIELD=6; ADD-LODR:ODR=56,CMD=ECHO,FIELD=7; ADD-LODR:ODR=56,CMD=NPI,NPI=ISDN,TON=INTERNAT; ADD-LODR:ODR=56,CMD=END;
and an LDAT.
ADD-LDAT:LROUTE=55,LAUTH=1,LSVC=ALL,LVAL=1,TGRP=55,ODR=56;
In the numbering plan, a digit pattern is configured according
to regulations, which is to be routed via the SIP carrier connection.
ADD-LDPLN:LCRCONF=LCRPATT,DIPLNUM=0,LDP="0"-"W"-"00"-"49"-"1801"-"30200"-"XXXX", LRTE=55,LAUTH=1;
INFO:
SIP Providers expect all digits en-bloc and do not
support overlap dialing. Thereby an alternative possibility to using
-X in LDPLN is to use -Z with corresponding time out (LCREOD in AMO
CTIME, branch CP1).
The following GKREG entry is not necessary and is only used for completeness,
as the LEGK does not resolve addresses:
ADD-GKREG:GWNO=1,GWATTR=INTGW&HG3550V2&SIP,DIPLNUM=0,DPLN=0,LAUTH=1;
The KNDEF entry cancels out the system part of the incoming
phone number:
ADD-KNDEF:NNO=1-40-155,TYPE=OWN,ISDNCC=49,ISDNAC=1801,ISDNLC=30100,ISDNSK=5;
