Calls are getting dropped by CUBE

[Madhura Joshi]

Hi,

Setup has CUCM 8.6.2 on which all the phones are registered. And those phones are using CUBE as a gateway for PSTN calls (CME, as SIP trunk is provided by STC)
60% of the PSTN calls are getting dropped and gets message from the CUCM: “your call cannot be completed as dialed..”

The call flow is as follows:

IP phone --> CUCM --> SIP trunk --> CUBE --> SIP trunk --> service provider

Any help regarding this, would be highly appreciated.

Thanks,

Madhura

Hi Madhura.

Can you please activate a debug ccsip messages on CUBE and capture the output when a call fails?

Thanks

Hi Anas and Carlo, thanks a lot guys for the reply.

Will capture the debugs. But it would be difficult to capture the output for the call failure. Because, 40% of calls are not being failed. So, I cant anticipate the output for failure/success call.

In fact, I have already captured the debugs from CUBE as well as CUCM. Will capture the fresh debugs and will ping here.

Thanks,

Madhura
