[Asterisk-Users] Cisco 7960 and Asterisk, I think I have a curly one here

[HILLMANN, DARREN]

I had the same problem recently, and it didn't have anything to do with
NAT.
Try looking at the port range in the rtp.conf file.  Make sure it
matches the port range configured on your 7960s.

Subject: [Asterisk-Users] Cisco 7960 and Asterisk,I think I have a curly
one here


Guys......

I have Asterisk CVS-NHEAD-03/19/05-21:56:28 running on a box here and
have a 
couple of Cisco 7960s and a Grandstream phone.

I can make calls from the 7960. When I get a call placed to the 7960 the
call 
is setup but there is no audio in either direction. This is for a call
placed 
on the local subnet between extensions so I doubt that it is a NAT issue

though I have tried a number of combinations of this to no avail.

I have tried firmware versions 6 & 7 on the Cisco phones, same result. I
have 
tried the phones on two other Asterisk installs and they work fine. I
have 
compared sip.conf with these and can see no differences.

If I configure the grandstream up to replace the 7960 it works fine.

I have noticed that the src port (TCP port on the phone) increments
during 
the session which seems to be the issue.

Anyone seen this before? Any assistance would be appreciated.

Regards
Peter 

Here are some of the settings.

Sip.conf for the extension:

[9001]
type=friend                     ; either "friend" (peer+user), "peer" 
or "user"
context=extensions
secret=9001
fromuser=Cisco          ; overrides the callerid, e.g. required by FWD
callerid=9001
host=dynamic            ; we have a static but private IP address
nat=never                          ; there is not NAT between phone and 
Asterisk
dtmfmode=rfc2833
canreinvite=no          ; allow RTP voice traffic to bypass Asterisk
incominglimit=5         ; permit only 1 outgoing call at a time
outgoinglimit=5
progressinband=yes
disallow=all
allow=ulaw
mailbox=9001


Phone config:

Loadid:  SW: P0S3-05-3-00  ARM: PAS3ARM1  Boot: PC030300  DSP: PS03AS30
