Alcatel trunk with asterisk problem on dial digit-by-digit

Asterisk Asterisk Support
1

Hi guys,

I have an Alcatel 4200 with a ISDN board pluged in the asterisk server with TE110P.

Input calls
VOIP Proider —> Asterisk —> Alcatel

Output Calls
VOIP Proider <— Asterisk <— Alcatel

In alcatel phones, users should dial 2 for take a line tone and can dial. At this point start my problems:

  1. When users dial 2 on phone (alcatel) they don’t received a dial tone, only receive a ocuped tone;

  2. When users make step one, in asterisk console i received this message:

!! Unexpected Channel selection 3
– Extension ‘’ in context ‘default’ from ‘027’ does not exist. Rejecting call on channel 0/31, span 1

If i configure in alcatel short dialing such: if user dial 3020 alcatel sent do asterisk a block number 31122332. In this case works fine.

How i can solve this problem ??

Bellow i list my extension.conf

[default]
ignorepat=>0

Internal Calls

Input Calls

exten=> 312120XX,1,Dial(Zap/g1/${EXTEN:-4})
exten=> 312120XX,2,Hangup

External Calls

exten=> _XXXXXXXX,1,Dial(SIP/${EXTEN}@voipprovider,60,Tt) # Local calls
exten=> _XXXXXXXX,2,Hangup

exten=> _0XXXXXXXXXX,1,Dial(SIP/${EXTEN}@voipprovider,60,Tt) # Long distance Calls
exten=> _0XXXXXXXXXX,2Hangup

exten=> _00XXXXXXXXXX,1,Dial(SIP/${EXTEN}@voipprovider,60,Tt) # Internacional Calls
exten=> _00XXXXXXXXXX,2Hangup

can you post more of the issue ? I dont know Alctel to well but from what I understand asterisk isnt getting all the digits ? Also how does Alctel work ? Does the user enter all the numbers and then it sends it or they hit 2 for an outside line and then it connects them to the line ?

Also for the line:

Input Calls

exten=> 312120XX,1,Dial(Zap/g1/${EXTEN:-4})

Are you trying to shave of the first 4 digits ?
If so you should try
exten=> 312120XX,1,Dial(Zap/g1/${EXTEN:4})

Are you trying to dial 0 or 2 from locals to get a second dialtone?

voip provider<-----Asterisk<------Alcatel<--------locals

You should have an insert 0 or 2 at Asterisk or have an access code repetition of 0 or 2 at Alcatel
