E1 Integration Between CUCM and MD110

[cdcat77]

Hello All,

Please I am trying to do an integration between a CUCM 11 and a MD110, the physical bridging is okay and the CUCM can make calls to the MD110 but am finding it difficult to make the MD110 call the CUCM, I have followed all the configs in this document

but still no luck. Any help would be appreciated.

Thanks
