[Asterisk-Dev] Segfault in parking and/or SIP routines

John Todd jtodd at loligo.com
Tue Jun 3 12:01:01 MST 2003 

Config:

SIP ATA-186 extension 2204
SIP Cisco 7960 extension 2203

Both are configured "canreinvite=no".  Both phones are behind a NAT. Call parking is turned on, extension 700, completely "out of the box" config for parking.  Music on hold is enabled.  Further configs available upon request.

*CLI> show version
Asterisk CVS-06/02/03-20:53:53 built by root at somewhere.something.com on a i686 running Linux

Symptoms:
I call 2203 from 2204.  Call is answered, progresses normally.  I hit "#" and get "transfer" prompt.  I type "700#" and I hear 'seven zero one'.  Extension 2204 immediately hears the music-on-hold while the digits are being read.  Then, I get a segmentation fault.
