Hi, could some one please help me with an issue I am having at a customer's. I have set up a sip trunk on the ip office and can make calls out fine, with two way audio, however when some one calls into the pbx there is one way audio. The receptionist can hear the person on the outside but they cannot hear her.

Ip Office rel: 8.0 (18)
L1: 10.90.142.3
ITSP: 10.90.142.4

Ip route
10.90.142.0
255.255.255.0
10.90.142.6 (customer router)

SIP URI
10.90.142.3
use internal data
use internal data
use internal data
none
17
0
32

L1 Network topology
open internet
public ip 10.90.142.3


If you need anymore information please ask. Thank you.

I doubt it's open internet, what are the transport settings for the trunk?

Hi amriddle, the transport part is setup like this,

ITSP proxy address: 10.90.142.4
UDP
LAN 1
Send port : 5060


The provider has an Ingate Siperator and keep telling me the only information I need is 10.90.142.4

If i change the network topology from open internet, then i lose audio both ways. This is my first time dealing with SIP trunks, and I can't figure out why it's working properly for outgoing calls, but not for incoming calls.

UDP
LAN 1
Send port : 5060

Change it from Lan1 to None as you already have build an IP route.


BAZINGA!

I'm not insane, my mother had me tested!

Thanks for the helps so far, I will get back to you with the results some time today.

Hi guys, still no luck with this. On incoming calls, the person calling into the pbx hears nothing, and gets a message "all network circuits are busy.
Here is a log of a successful two way conversation outgoing:

You need to troubleshoot this issue yourself really, it is network/routing related. If on an analogue line you hear crackle you check the cabling as that's the medium by which the service is delivered, with SIP the delivery is by a network connection, when you get no/one way voice issue you need to look at the network and routing as such there is little we can suggest beyond confirming your config is correct, traces don't show the audio stream, but you can see them in monitor. Also capture with wireshark on a mirrored port, if that has one way audio when played back then it isn't the system as you've ruled that out.

However this statement....

If i change the network topology from open internet, then i lose audio both ways. This is my first time dealing with SIP trunks, and I can't figure out why it's working properly for outgoing calls, but not for incoming calls
Click to expand...

Putting it to the correct setting stops it working means something is wrong, no point leaving it on the wrong setting as that's probably causing the one way audio and no amount of config can fix it if that's the case, you need it on the correct setting then try getting it working fully even if it means also losing outbound in the short term :-)

Hi, just letting you guys know that I finally got this working...... all this time it was a problem from the provider's side. They said that they made the packetization time 10 seconds and that made everything work.

Nice, thanks for letting us know.
Don't forget to send them a bill for hours of troubleshooting.
