Yes meanwhile I have found that you guys did some job around alarmreceiver()
and I have tested the asterisk trunk. Unfortunately I got the same
I have enabled the DTMF debuging and what I see is that asterisk gets
Mnually confirmed that the message sent is:
11111816280004 [pause] 11
Asterisk waits to get 16 digits in total and the last 11 is actually the
next retry alarm pannel is sending
So it seems Asterisk is missing few tones at the end.
I have experiment with dtmf_hits_to_begin and dtmf_misses_to_end from
dsp.conf with no improvement

I have confirmed that my SIP link is using ulaw codec.
Or did I misundestood your remark?
To clarify on the picture I have sent on my first email 'Asterisk device 1'
is an embedded PBX runing Asterisk 1.4 and having FXS interface.
I am getting to the point that this device is modifying my TDM stream
and my alarmreceiver on the PC box is not what making the issues.
I will try with an ATA instead hopfully this time get my Contact ID
Thank you for the help!
