[asterisk-users] Sipgate trunk doesn't bridge with other trunk, but works with local extensions

Hello list,

My setup is as follows:

Trunks: 2 sip trunks, one with voipcheap.co.uk, one with sipgate.co.uk
Extensions: 1 hardware sip phone
Asterisk: 1.8.7.0

Everything is working fine, except bridging between the sipgate and 
voipcheap trunks. I'll explain:

1. If I call from an external phone my sipgate landline number, it 
connects to my internal hardware sip phone/extension and works fine.
2. If I use my hardware sip phone to make outgoing calls through the 
voipcheap.co.uk trunk - it all works fine.
3. However, I want the call coming in through the sipgate trunk to call 
my mobile phone through the voipcheap trunk - this is not working. It 
will ring the mobile number, but when I answer there is no sound at 
either end.

I assume it is not:

1. A NAT problem, otherwise it would cause problems when making calls 
through voipcheap, or receiving through sipgate (but I could be wrong).
2. A codec problem - as I've forced everything on alaw

I can't see any errors in the console either. Please find below my 
sip.conf, extensions.conf:

#/etc/asterisk/sip.conf

verify your codec are the same on both trunks. make sure the both trunks 
are using the same codec. make sure you have the correct ports open. make 
sure you force all udp traffic to flow through your astrisk switch as 
well.


Thanks

Hello list,


My setup is as follows:


Trunks: 2 sip trunks, one with voipcheap.co.uk, one with sipgate.co.uk

Extensions: 1 hardware sip phone

Asterisk: 1.8.7.0


Everything is working fine, except bridging between the sipgate and 

voipcheap trunks. I'll explain:


1. If I call from an external phone my sipgate landline number, it 

connects to my internal hardware sip phone/extension and works fine.

2. If I use my hardware sip phone to make outgoing calls through the 

voipcheap.co.uk trunk - it all works fine.

3. However, I want the call coming in through the sipgate trunk to call 

my mobile phone through the voipcheap trunk - this is not working. It 

will ring the mobile number, but when I answer there is no sound at 

either end.


I assume it is not:


1. A NAT problem, otherwise it would cause problems when making calls 

through voipcheap, or receiving through sipgate (but I could be wrong).

2. A codec problem - as I've forced everything on alaw

What kind of firewall are you using?

If I was you I would take the FW out of the equation and test this. If
possible put your server on a public IP and check.
