Cannot dial out / in CUBE with ITSP

Yannick Vranckx
Level 2
Level 2

Hello,

 

I'm facing an issue here were i can't dial out towards the ITSP from my Cisco UBE

I've been assigned a number range to test, and i have been trying to dial out. The call does not go through, it hits the CUBE from the CUCM but then it seems to die.

The invite is received from Call Manager (10.3.26.11) and relayed by the CUBE, but it seems that he is relaying it back Call Manager??

 

The dial peers are setup like this:

 

CUBE#sh run | s dial-peer

dial-peer voice 1 voip

description Outbound All

translation-profile incoming SIP-IN

preference 1

destination-pattern +.T

session protocol sipv2

voice-class codec 1

voice-class sip bind media source-interface GigabitEthernet0/1.90

dtmf-relay rtp-nte

no vad

 

GI0/2 is a point to point VLAN with the provider router in it 

and Gi0/1.90 is straight over the internet the Call Manager.

 

I have attached 2 other outputs

 

- debug voip dialpeer all

- debug voip ccapi inout

 

It seems that he says incoming dial peer 100? Outgoing call from Callmanager to CUBE. But it says that the outgoing dial-peer = 1, that seems OK?

 

Could someone assist me in this?

 

 

Thanks

Are you allowing sip to sip connections? Make sure you have voice service voip and allow sip to sip.

Many SIP providers will only allow outbound calls if the calling number is one that you own and is assigned to that SIP trunk by the provider. Make sure the calling number is one assigned by the carrier.

Dial peers look OK.

The disconnect cause code is 3 = no route to destination.

 

 

Hello,

 

Thanks for the information

 

What i have already found out was:

In my SIP-UA i specify a sip server, the provider told me to use a dns name and not IP. Otherwise they deny the call. So i need to enter that in.

Under SIP-UA:

sip-server: dns:domain.com:5060

But i forgot to resolve this name locally on the router, so i added the following command to the router:

ip host domain.com X.X.X.X

 

Now i am actually getting a response from the provider, its still not working. I'm now getting SIP 403 Forbidden, so i will need to contact them to see what i am missing.

I will post the output asap

 

Thanks,
