CME - Conference does not works

Hi everybody,

I have configured a CME for a small office, and during the tests the conference did not work. I have re-check the configuration and cannot find the problem. I have attached the configuration of CME here. 

Does anybody knows if can be a bug of IOS for this router 2801 or a mistake in the configuration ?

GW uptime is 2 minutes
System returned to ROM by power-on
System restarted at 19:04:37 GMT-2 Mon Jan 11 2016
System image file is "flash:c2801-advipservicesk9-mz.151-4.M10.bin"
Last reload type: Normal Reload

The IP Phones are Cisco 7942 SCCP

Best regards,

Daniel

Daniel,

Your config indeed looks correct, are the profiles registered with your CME? Can you post "show dspfarm all"?

Hi Chris,

All 2 profiles (XCODEC and CONFER) are registered, however, I will return this Friday to the customer and  I can collect more information.

I have check "show voice dsp error" and there is no error.

Cisco 2801 (revision 7.0) with 221184K/40960K bytes of memory.
Processor board ID XXXXXXXX
2 FastEthernet interfaces
1 Serial(sync/async) interface
1 Virtual Private Network (VPN) Module
4 Voice FXO interfaces
2 DSPs, 24 Voice resources           (16 PVDM Slot 0 and 8 PVDM Slot 1)
DRAM configuration is 64 bits wide with parity disabled.
191K bytes of NVRAM.
125440K bytes of ATA CompactFlash (Read/Write)

Best regards,

My question was not about phone registration, but DSPFarm registration. Since you are using hardware conferencing the defined profiles register with CUCM/CME via SCCP.

Hi,

Following the show dspfarm profile output:
