Asterisk Inserting random digits in Dial!

Asterisk Asterisk Support
1

Eeeeck! Asterisk is inserting random digits in dialed numbers.

So far I’ve seen it insert a 2 after the STD (area) code and insert an extra 6 or 7 in the STD code. It’s pretty repeatable although the inserted number changes.

My Config is: Asterisk 1.4.5, Zaptel 1.4.3, Digium TE205P (rev 02).

There’s an ISDN PBX on the second span and a BRI euroisdn on the first.

Calls from the ISDN PBX (Network Alchemy Argent Office FWIW) get put into the ‘alchemy’ context which contains:

    [alchemy]
    ;
    include => dial_pstn
    ;
    ;   Dial Out to PSTN
    ;
    [dial_pstn]
    exten => _X.,1,Dial(Zap/g1/${EXTEN})
    exten => _X.,2,Congestion
    ;

Pretty simple and didn’t cause problems before I went to 1.4.4/5

Here’s the console log from a failing call (non-significant numbers obscured to protect the guilty!).

– Executing [017332235xxx@alchemy:1] Dial(“Zap/46-1”, “Zap/g1/017332235xxx”) in new stack
– Requested transfer capability: 0x00 - SPEECH
– Called g1/017332235xxx
– Zap/1-1 is proceeding passing it to Zap/46-1

As you can see, the ISDN PBX passed 01733 235xxx but Asterisk decided to dial 01733 2235xxx (an extra ‘2’ after the STD code).

Arrrrrrgh!!! This is driving both us and the people who’re getting
called incorrectly potty :frowning:

Can anyone help? Thanks in advance.
