Im new to SIP. I just want to confirm from the SIP experts, if my setup is correct.
Primary Active: IP Phone SCCP <-> CUCM 9.1 <-> H323 <-> VG2901 (CUBE) <-> ISDN DID
Testing: IP Phone SCCP <-> CUCM 9.1 <-> SIP Trunk <-> VG2901 (CUBE) <-> SIP DID
ISDN is currently active and I'm preparing SIP for the customer so we can cutover later when SIP is ready. At the moment, inbound works via SIP working side by side with the ISDN. Calling the SIP DID pilot # the call hits CUCM and the phone rings. For outbound I have created a route pattern in CUCM that goes out via SIP trunk then to the CUBE then to SBC. No luck with outbound call. I get a fast busy as soon as the called number matches the CUCM route pattern.
Gateway registers to VG2901 (CUBE) as IP Address 192.168.1.254.
SIP Trunk registers to the same VG2901 (CUBE) as IP Address 192.168.1.254. Im not sure if this is causing the problem, having the same IP Address in CUCM for both H323 VG and SIP Trunk to the same VG/CUBE.
SIP traces provide key information in troubleshooting SIP Trunks, SIP
endpoints and other SIP related issues. Even though these traces are in
clear text, these texts can be gibberish unless you understand fully
what they mean. This document attempts to br...
