I have 10 fxo port configured in H.323 in CUCM6. My doubt is can I forward call comming to these ports to a single DN (like receptionist) in 7960 which got six lines or do I need to configure 10 defferent DN for each lines and forward the call to them.
You said you had CUCM6.
You can use just 1 DN, so just adjust the maximum number of calls to +10 and busy trigger also to +10 value.
It works both ways, you can also have 6 DNs in the phone and distribute the calls between them.
It really depends on how you want/need to configure it.
if this helps, please rate
