Phones registered to different subscriber cannot communicate

iftikharsyed_2
Beginner
Beginner

We have 4 CUCM in PUB-SUB scenario

1 -PUB and 3 SUBs with cucm 6.0

everything was working fine but from last few days we are facing an issue,

Phones registered with Subscriber A can communiate with phones on Subscriber B and C both

Phones registered to Subscriber B can commnicate with subscriber A but not Subscriber C

Phones registered to sub Subscriber C cannot communicate with subscriber B but they can communicate with subscriber A

There are times when subscriber C phones can communicate with Subscriber B phones but its very rare.

I have verified DB replication status and its 2

I have tried to insert phones from subscriber C Admin page and it works.

There no latency or packet drops issues between Subscriber to Subscriber and Publisher to subscriber.

Any suggestion to solve the issue.

Hi,

Thanks to all of you for replying,

As i posted earlier, there are no issues with WAN link, link between these two sites is STM1 link with no packet loss and latency around 12ms.

MTU for the network path is 1500.

If it is a Bad NIC issue then problem should occur between all three sites.

Vivek,

Utils diagnose test is not a valid command in CUCM 6.

Unfortunately we don't have essential software support at this moment to open TAC case.

Kindly let me know which DSL trace can be used to check issue with SDL linkOSS. as this is the only error displayed on RTMT application Log

Regards,

Iftikhar Ahmed

Hi,

I have checked realtime SDL traces and i see following
