Problem connecting avaya sip server and astersik

Hello everyone,
I have some problem running asterisk together with avaya sip server.

This is the topology I have:
P1 is normal phone, P2-4 are VoIP phones.
Asterisk is listening on two interfaces - one is local and one is opened to the net.
Rtp transport and the sound exchange is handled by media server.

+----+        +-------------+
| P1 |--------| PBX + media |
+----+        +-------------+
                     |
                     |
              +-------------+       +----+
              | avaya sip   |-------| P2 |
              +-------------+       +----+
                     |
                     |
                     |
              +-------------+
              |  Asterisk   |               WAN
-------------------------------------------------
              |             |               LAN
              +-------------+
                 |       |
                 /       \
       +----+   /         \   +----+
       | P3 |--+           +--| P4 |
       +----+                 +----+

P2,P3 and P4 can make calls together easily.
P2 can call with P1, but P3 and P4 cannot.
Also I can call Asterisk from P1 without problems.

Here is my sip.conf:

[general]
Port=5060
bindaddr=0.0.0.0
srvlookup=yes
nat=no
allow=all
context=users
dtmfmode=auto
notifyringing=yes
defaultexpiry=300

externip=xxx.xxx.xxx.xxx
localnet=192.168.26.0/255.255.255.0

register => 3076@avaya.proxy

[avaya.proxy]
type=peer
context=proxy
host=xxx.xxx.xxx.xxx
canreinvite=yes
secret=secret
nat=no

[p3]
type=friend
context=users
callerid=VoIP Phone no.1
nat=no
canreinvite=yes
host=dynamic

[p4]
type=friend
context=users
callerid=VoIP Phone no.2
nat=no
canreinvite=yes
host=dynamic

I would have suspected misconfiguration of avaya server, but because P2 can connect with P1 I guess there must be something wrong with asterisk configuration.

Thanks for any help you can offer
Regards
Martin

Please increase the cli verbosity level to 9, try a call from P3 to P1 and then post the cli output.

Cheers.

Thanks for quick response…

I have set verbose output with ‘core set verbose 9’ and that’s what I got:

== Using SIP RTP CoS mark 5
    -- Executing [s@users:1] Dial("SIP/5061-00744900", "SIP/p3") in new stack

--- set_address_from_contact host '192.168.26.4'
--- set_address_from_contact host '147.x.x.50'

In my extension.conf I have this line:

exten => s,1,Dial(SIP/p3)

This is a result of ‘sip show channel’ for both channels:

And when running tshark I see ICMP packets with ‘port unreachable’ for 147.x.x.57(the media server) :confused:

If it can help, I will post sip debug output as well…

Seems to me if you want to call P1 through the avaya pbx you should put something like this in your extensions.conf:

exten=>12345,1,Dial(SIP/avaya.proxy/P1)

You called the P3 phone, please try call the P1 phone from the P3 phone and post the cli output.

Cheers.

Marco Bruni

Addendum to P1->P3 situation:
It may be not that clear, but I have successfully make the call, but I have no audio and I keep getting ICMP port unreachable for rtp packets…

As for P3->P1:
when calling P1 from P3 I use it just like you have written.
(note that P1 has number 3066)

exten => 3066,1,Dial(SIP/avaya.proxy/3066)

This is cli output

== Using SIP RTP CoS mark 5
    -- Executing [3066@users:1] Dial("SIP/p3-0074db00", "SIP/avaya.proxy/3066") in new stack

  == Everyone is busy/congested at this time (1:0/1/0)
    -- Auto fallthrough, channel 'SIP/p3-0074db00' status is 'CONGESTION'

And here is the SIP debug P3->P1

About P3 -> P1 call, seems the problem is that avaya can’t find the sip endpoint (or the called sip endpoint doesn’t accept the call), so it’s not a problem in the Asterisk side.

Cheers.

Marco Bruni

Yeah… that’s what I was thinking for the first time too… But what I don’t understand is how come that the P2->P1 call is working. I am calling the same user :cry:

About another issue - no sound when doing P1->P3:
Consider it resolved - it is a problem of SJPhone. My own program built upon sofia sip stack as well as x-lite is working correctly.

Sound issue again :unamused:

I have noticed that there seems to be issues whenever there are lines like these in SDP that P3 sends to Asterisk(just a guess, but I couldn’t find any other reasonable differencies between sip messages that work and that don’t work).

Media Description, name and address (m): audio 3000 RTP/AVP 0 127
Media Attribute (a): rtpmap:0 PCMU/8000
Media Attribute (a): rtpmap:127 telephone-event/8000
Media Attribute (a): fmtp:127 0-15

Namely the last two ones… (Neither x-lite nor my application include them)

When these lines appear, Asterisk starts new INVITE after the first one is successfully finished, but this time it includes in SDP the local address of P3.
i.e. First INVITE from avaya is responded to with 200 OK and asterisk’s address 81.x.x.93 in SDP.
Then asterisk sends a new INVITE to avaya with address 192.168.26.9 in SDP.
(This is not happening with x-lite or my app)

As a result I receive some four or five rtp packets and then it stops…

Is this a bug or some mistake in my configuration?

Try set canreinvite to no in the avaya peer definition.

Cheers.

Marco Bruni

That solved the issue! Thank you very much!

Martin

Hi,

i have similar problem in same configuration like you, but i cant call from P3 to P1. Calls from P1 to P3 works.

 -- Executing [7013@default:1] Dial("SIP/test-085c1e78", "SIP/7013@avaya-out|20|tT") in new stack
    -- Called 7013@avaya-out
    -- SIP/avaya-out-086060f8 is circuit-busy
  == Everyone is busy/congested at this time (1:0/1/0)
  == Auto fallthrough, channel 'SIP/test-085c1e78' status is 'CONGESTION'

Any idea how to fix it?

Greetings
