I have a VG224 FXS ports registered as MGCP in CUCM 9.1. All the ports are showing registered in CUCM. But Some of the ports have no dial-tone or ring. I tried re-configuring the ports , resetting and even tried rebooting the VG224 itself , but nothing came positive. When i do " Show voice-port summary " , i can see the status of the port is ringing when i call this number . There is no problem with cabling. Where could be the issue ?
Hi Carlo ,
Which is the firmware version of VG224?

Have you tried to reload the VG?
Answer: Yes tried it couple of times and more and tried resetting the ports from CUCM and also shut/noshut from VG224 Cli
Are non - functioning ports contiguous?
Answer: We have 8 VG224 . Non-functioning ports are random. 1st VG224 we have 3 random ports not working. 2nd VG224 we have like 4 random ports not working.
NOTE : These ports were working before. When we get complaint from enduser , we have to change the ports for him.
Did you try to check the telco cable?
Sometimes some pins may be faulty .
Another test is to go directly on the analogue pathc panel and take the non working pair and test them with an old analogue telephone.
Please let me know
