Internal call answered externaly


(Marco) #1

Hello Community,

can someone help me what to set, so FreePBX does not try to answer an internal SIP call to an external adress?
In Asterisk Console the following is logged if i try to call internally:

**<— Received SIP request (364 bytes) from UDP:192.168.189.1:5060 —>
ACK sip:test@192.168.189.39 SIP/2.0
Via: SIP/2.0/UDP 87.24.76.134:5060;rport;branch=z9hG4bK2230040591F0E6B9
From: sip:anonymous@fritz.box;tag=3472A8F40AB65AAC
To: sip:test@192.168.189.39;tag=z9hG4bK2230040591F0E6B9
Call-ID: 820AEE16390A515A@87.24.76.134
CSeq: 66 ACK
User-Agent: AVM FRITZ!Box 7490 113.07.12 (Jul 3 2019)
Content-Length: 0
**

At the end of the call Asterisk tries to send packets to the ip in the third row (via) althouth the call comes from internal network.

Could someone please help me how to disable the external thing, I just want to use FreePBX fpr my internal network.

Thanks in advance, best regards
Marco

Check your NAT settings

Hello arielgrin,

thanks for your reply.
I allready tried almost every NAT-Setting I found in FreePBX WebUI, could you or someone else who knows, guide me to the correct point of config?

thanks in advance
best regards

You would first need to explain your setup in order for us to help.
Please describe your setup, like hosted or on-premise, devices directly connected to FreePBX or behind a NAT device, etc etc.

Thanks again for your reply,

I have a blank RasPBX installation on a Raspberry 3B+.
I use an AVM Fritz.Box to do SIP-URI calls from an DECT-handset internally to that RasPBX.

I want RasPBX to only play an announcment and hang up after that.
Probeably FreePBX is much to big for that, but I didn’t find anything smaller :wink:

Thats all, just “internal answermachine with a hangup-function” :wink:
No NAT no external SIP-provider or incoming calls from the WAN-side of the fritzbox.

I didn’t change anything to the default RasPBX config, except for the extension that should answer and the allowing for anonymous incoming calls.

I can see Asterisk is routing the call to the right extension, plays the announcment ant hangs up that call, but the handset doesnt hear the announcement and also does not recieve the hangup command from asterisk.

in tshark on raspberry and asterisk log I saw somehow asterisk tries to contact the WAN-IP of the router.

Hope you can help me
thanks i advance
best regards
Marco

Please post internal ip of asterisk and fritz box


(Marco) #7

Fritzbox: 192.168.189.1
FreePBX: 192.168.189.39

The IP in the “Via:” line is my WAN-IP (changed ;-)) but i don’t know from where FreePBX gets it.


(Joshua C. Colp) #8

FreePBX isn’t getting it, that is provided by the remote side.


(Marco) #9

Are you sure?
I’m asking because 192.168.189.1 is a Fritzbox without a WAN interface, its just a DECT-base in the internal network, altought it has access to the internet, I can’t believe he would tell my WAN-IP to the FreePBX.

Best regards
Marco


(Joshua C. Colp) #10

The message you see is received from the device, and what is output is what is received. There are various mechanisms (such as STUN) that allow a device to determine its public IP address and then use it. Providing an actual full trace would provide further insight into what is happening.


(Marco) #11

Thanks jcolp, for the information.
It seems you are right and the information is really sent by the fritzbox.

Do you think there is a way to tell FreePBX to send the answer to the source-ip instead sending it to the “Via” header?

Because i don’t think I can get the fritzbox to change its behavior :wink:

Thanks in advance
Best regards
Marco


(Joshua C. Colp) #12

There are options in Asterisk to allow such a thing. I do not work on FreePBX so I do not know where/how they are exposed, but they do exist.


(Marco) #13

OK, thank you very much.
In FreePBX there is an option Custom Extension, maybe one can do it from there?

Best regards
Marco


(Lorne Gaetz) #14
; The RFC 3581-defined 'rport' parameter allows a client to request that Asterisk send
; SIP responses to it via the source IP and port from which the request originated
; instead of the address/port listed in the top-most Via header. 

the force rport param is accessible via the Advanced tab, NAT settings for a chan_sip extension.


(Tom Ray) #15

This might be an issue since this is to a Fritz!Box which means this could be a trunk not an extension. As long as this is a Chan_SIP trunk then changing the nat=comedia,force_rport is what needs to be added to the trunk. However, if this is a Chan_PJSIP trunk that is different as you just can’t add any setting you want you have to use the options presented and force_rport is not a setting for PJSIP trunks. Probably because the logic behind that was “It’s a trunk, to providers. They aren’t behind NAT”.


(Lorne Gaetz) #16

I see it as an option, core ver. 14.0.28.14 on pjsip trunk advanced tab:


(Marco) #17

Thanks to all for your help!

@lgaetz: that sounds exactly what should be the problem
but no matter what I set in chan_sip or even pjsip extensions rport/nat setting, asterisk always sends the packets back to the top most Via header ;-(

maybe I have do do some asterisk/freepbx reloads of configuration after setting such things?
for me it seems the settings just aren’t used

thanks for your help
best regards
marco


(Marco) #18

Hello again,

regarding to my problem I logged what asterisk does when a call from the FritzBox arrives,
seems that eyerything is working as expected until it comes to ending the call, maybe one of you can see what is the problem (WAN-IP changed ;-)) the last BYE request is repeatet 5 times:

thanks in advance
best regards
marco

(Joshua C. Colp) #19

The “rewrite_contact” option needs to be set to “yes” in order to have requests sent to the source IP address/port instead of what the remote side says (which in this case is a public IP address and port). I don’t know how that is done in FreePBX, but that would send the BYE to the right IP address/port.


#20

This is probably due to the fritz box having some type of SIP NAT helper / ALG
