Dear chan_ss7 users,
I've bumped into a problem when using chan_ss7 1.0.0 in Germany.
Overlapped dialing didn't work properly.
The relevant ss7 configuration reads
...
enable_st => yes
t35 => 4000,st
Asterisk configuration reads
...
exten => _0X.,1,Dial(ss7/myss7/${EXTEN:1})
...
The DTM switch is configured to signal incoming calls to Asterisk when
it receives min. 7 digits.
If I dial a number longer than 7 digits using an analog handset.
Asterisk tried to make ougoing call as soon as it has received 7 digits.
Everything is OK if I use a digital handset, where the number is sent as
a block.
After having traced the debug output I've found out when I call using
analog handset the inmsg->iam.dni.complete is set to 0 but the function
process_iam() calls check_iam_sam(pvt) anyway.
I've modified the code a bit and it works fine for me now. The
modification is to be found in the attached patch file.
I'm very grateful if someone can take a look at my modification and
gives feedback.
Cheers,
Hoai-Anh
