[asterisk-users] Asterisk + iaxmodem + hylafax makes sometimes wedged for hylafax

[Gianni Fioretta]

First of all, thanks for the response :)
Noticed are ok, I've added maxregexpire=300 in iax.conf, as shown below...

We use ubuntu 12.04, asterisk was installed from its repository:
srv-faxserver*CLI> core show version
Asterisk 1.8.10.1~dfsg-1ubuntu1 built by buildd @ yellow on a x86_64 running Linux on 2012-04-24 12:47:04 UTC
