So looks like noone out there know how to setup a sip trunk between two sip servers?

 

[Sympology]

Think you need to actually describe what you want to do, what you have tried, what you hope to achieve etc etc...

You have posted what looks like a very vague statement.

For exapmple, I need to set up a SIP trunk from an Asterisk server, to xyz. I have the trunks set up, and they are connecting, but I am unable to get any audio.

I don't use Asterisk, but doesn't mean I couldn't help on question like.

The more specific your question, the better the answer you will get....

thanks for the reply.

Ok you are very correct.

The goal is to connect a sip server here in US (asterisk) to another sip server (APPLICO) in another country China.

this is my sip.conf outbound trunk
type=peer
secret=*********
username=********
host=sip.****.com.cn
fromuser=*********
canreinvite=no
nat=yes
disallow=all
allow=gsm
allow=ulaw
allow=ilbc
allow=g729

 

[Sympology]

Not sure about China settings, but you may want to allow aLaw as uLaw tends to be US and Japan.

What sort of link do you have...

I would use IAX trunking instead of SIP.

TRUNK NAME
server111


allow=all
context=from-internal
host=[enter the ip address of server222]
insecure=very
qualify=yes
type=friend

server222

TRUNK NAME
server222

PEER DETAILS
allow=all
context=from-internal
host=[enter the ip address of server111]
insecure=very
qualify=yes
type=friend

Isn't AIX trunking only between * boxes?

I have setup trunks to traditionl phone systems using just the trunk that he has already setup. It could be the remote end. Never worked with that brand of system.

 

[busster]

Yes, IAX is a asterisk protocol, but most sip servers will utilize IAX as well.

 

[shazzam1]

I still have not had a chance to make this work any help is appreciated.

I haven't come across any SIP servers myself that support IAX2 except for Asterisk.
