[Asterisk-Dev] AGI drops first DTMF digit

[goldfita at rose-hulman.edu]

Greetings,

I am using the c code from http://home.cogeco.ca/~camstuff/agi.html
(modified to break on #) as an AGI script.  When using a cisco 7960 phone
over SIP, there is no problem.  When using a grandstream phone over SIP,
the first digit is always dropped.  I get the same behaviour for GET DATA.
 It is also the same when using python.  Neither phone has any problems
when using the voicemail module.  It seems to be an AGI thing.

Example:
send>GET DATA welcome (from AGI)
send>123456# (DTMF digits)
recv>23456 (to stdout from grandstream)
recv>123456 (to stdout from cisco)

My build:
Asterisk CVS-v1-0-11/04/04-15:50:19 built by root at asterisk on a i686
running Linux

Any ideas?  thanks
