[Deepika Nijhawan]

Below is required info:

 

1. Which version of asterisk ,dahdi and libss7  you installed

Asterisk 1.6.2.7

DAHDI Version: 2.3.0 Echo Canceller:

libss7 version: 1.0.2

 

2. OS Kernel Version

Centos 5.4

 

[root at asterisk4.uk:~]$ uname -r

3.IPTables and SELinux Status

IPTables is fine. My softphone's ip range is allowed. This was working
before with ISDN.

 

[root at asterisk4.uk:~]$ cat /etc/sysconfig/selinux

# This file controls the state of SELinux on the system.

# SELINUX= can take one of these three values:

#       enforcing - SELinux security policy is enforced.

#       permissive - SELinux prints warnings instead of enforcing.

#       disabled - SELinux is fully disabled.

SELINUX=disabled

# SELINUXTYPE= type of policy in use. Possible values are:

#       targeted - Only targeted network daemons are protected.

#       strict - Full SELinux protection.

SELINUXTYPE=targeted

 

4. Codec Status

I am dialing from softphone -> asterisk -> telsis using alaw codec.

 

5.SIP.conf and extension.conf  information

 

sip.conf:

username=448714349151

secret=deepika

6.

Even if I enable below line in system.conf?
