Hi all,
Firsts of all, let me say that I'm new to asterisk. I have some time
suscribed to the list reading a lot of your messages and trying to learn a lot.
The case is: last week I installed an asterisk server in the following
scenario:
PBX --- CISCO_ROUTER ---- ASTERISK
The calls that are routed within the asterisk work perfect, there is not
problem.
However, the calls that are from Asterisk to the PBX (or viceversa) have a
kind of noise every three seconds or so. I have tried different codecs without
success and I don't know what else to try. In this moment I only count with the
codecs g711ulaw and g711alaw in the router, I don't think bandwidth is a
problem in this moment.
This is the output while a call is been used:
---- cut here ----
VoIP*CLI> sip show channels
Peer User/ANR Call ID Seq (Tx/Rx) Form Hold Last
Message
X.Y.Z.K 2. 83E9477C-3A 00101/00101 ulaw No Rx: ACK
1 active SIP channels
---- cut here ----
And this is an small excerpt of my router:
--- cut here ---
dial-peer voice 11 voip
application voip_asterisk
destination-pattern 280.
session protocol sipv2
session target ipv4:X.Y.Z.K
codec g711ulaw
ip precedence 5
--- cut here ---
Can any one point me what else can I try?, what would you do in my case?
Thanks a lot.
Alejandro,
