Can Not Complete Conference

[jpiznar569]

I have read many of the posts on this topic but cannot seem to find the answer to my problem.  I can't make conference calls with anyone outside of the building.  Internally I have no problems.  We upgraded our router to ver. 15.0-1 and call manager 4.1(3).  We are using 7940, 1941,7960, and 7961 IP Phones.  Attached is the show run from our 2851 cube router.

Thanks,

John

Hi John,

Seems that you are missing the ephone-dns used for conferencing. Something like this:

conf t

ephone-dn 1 dual-line

number 4444

conference ad-hoc

Please refer to:

Tere,

The file you sent me is for CME.  Does it matter that I am not using call manager express?  Is the router config the same?

Hi!

Sorry, my bad I don't know why I assumed you were using CME. If you have CUCM this can be an issue with the region and codec you are using. Please check if you are using G.711 or G.729 to the PSTN and see if tou have a transcoder available.

Please check if the proper GW is configured on the MRGL to route the outbound calls properly.

Regards,

Tere.
