[cisco-voip] Outbound Dial with Carrier SIP Trunk

Thu Oct 2 16:03:35 EDT 2008

It should go 

SIP 100 - Invite

SIP 183 - Session Progress

SIP 180 - Ringing

Yours appears to be 

SIP 100 - Invite

SIP 183 - Session Progress

SIP 183 - Session Progress

SIP 183 - Session Progress

What is the codec on the internal side?  I'm seeing RTPMAPs on your 10
network for 8 codecs, and incoming from your provider 3 supported codecs
(G711ulaw, G711alaw and G729).

It appears that your provider is attempting G729 to connect and
continues to send you SIP 183s.

Can you send a sanitized config?

Also, I removed the debug from below so the list moderator won't have to
keep approving these for size.

Where are you setting the codec?  The line below says you are not using
VCC, are your dial peers specifying a codec?

Matt,

Not sure what means.  I see g726r32 is selected as a codec...but why?  I
don't have the set as my codec on the dial-peer and the carrier is set
(or supposed to be) to the same as me.  I guess I'm not really sure what
that line is telling me.

Selecting Dynamic Payload : 96 for Codec: g726r32

Hey All,

We're in the process of trialing a SIP trunk solution from our provider,
PAETEC.  I followed the Cisco docs for configuring a CUBE, but we can
only receive calls and not place them.  The setup is CUCM 6.1(2) -> SIP
Trunk -> CUBE (2811) -> SIP Trunk -> PAETEC SIP Gateway.  I'm very new
to SIP and am trying to analyze the output from debug ccsip all.
Nothing is jumping out at me as the exact reason why the calls outbound
from our CUCM aren't working.  Anybody have any ideas?
