SIP 500 Error on CUBE and CUCMBE

Answered Question

So Inbound calls works fine with no issues, however outbound I'm getting a busy signal when I dial out to the PSTN, not your typical CSS fast busy but busy like someone who does not have call waiting. Here are the debugs below.

SIP trunk between CUCMBE and CUBE are MTP codec method is 711ulaw, in my Regions my CUBE is set to g729r8, and phones are set to 711ulaw. I'm not sure what's happening but it's very frustrating.


Anyone can be of assistance?

Looking at your config..The outbound dial-peer that is matched is configured as follows


dial-peer voice 101 voip

description 10-digit local calls to Intelepeer

destination-pattern ^[2-9]..[2-9]......$

session protocol sipv2

session target sip-server------------------------------------

session transport tcp

voice-class sip early-offer forced

voice-class sip profiles 100

dtmf-relay rtp-nte

no vad


From your config, the destination-pattern is pointing to a sip-server, however there is no configuration on your gateway to define the ip address of the sip server. This is configured under sip-ua


voice service voip

sip-ua

sip-server ipv4:10.10.10.10--------------where 10.10.10.10 is the ip address of given to you by your ITSP

Kenneth,


Th gateway is not sending out the INVITE..I need the sh run of the gateway to see your setup...What is the call flow?


Is this sip to sip or sip to ISDN?


cucmbe--sip----cube--sip--itsp?

Yes I discovered that when I got home today. I thought it was in the config but it wasn't. I applied it to my config and all is working. Thank you for assisting me with this.
