The phone does not need a DID to be able to dial out, make sure it has proper Calling Search Spaces defined on the device and DN, as well as device pool if you are using local route group routing (compare to working ones). If that is the same you will need to provide us with debugs from the voice gateway, so let us know if you have a PRI, SIP trunk or POTS lines.
When I checked out the DN config of phones with direct lines (19xx) I saw that it has an input of 662XXXX on the "External Phone Number Mask" which I thought that 662 (company line) XXXX (4 digit directline).
Now, I tried to place the same input 662XXXX on the local phones (20xx) and check if it could make an outgoing call but unfortunately it didn't.
Upon several minutes of thinking, I thought to edit the phone mask input 662XXXX and insert in between a 19xx direct line and give it a try.
For example, I used the direct ext number 1998, on the phone mask box of a 20xx IP Phone, I placed 6621998XXXX and gave it a try.
In theory it goes like this: 662 (Company line) > 1998 (Direct line) > XXXX (Local line of 20xx)
The local line (20xx) will be using or will pass thru a Direct line (19xx) to make an outside call.
I gave it a shot and it worked!! Yeah!!
I made several testings, I tried to make an outside call using the IP Phone with ext 1998 and while on the line I used the local 20xx which I configured with 6621998XXXX to make another outside call.
On my expectation, the call from the 20xx should not go thru. It should have resulted to a "busy tone" or "cannot make this call" message or even cut the line of 1998.
But it didn't! Both outgoing calls from 1998 and 20xx are on the line simultaneously!
I tried it vice versa, first made an outgoing call using the 20xx that I configured, then while on the line I used the ext 1998 phone and made another outgoing call and they both ran at the same time!
It didn't cut the line of 20xx, it didn't result to a busy tone or a "cannot make this call" message.
Internal calls are good too, you can call directly either way just by dialling their 4 digit extension numbers.
*But still, those IP Phones with 20xx cannot receive direct calls like before. Outside callers would still need to contact a 19xx then it can forward it to a 20xx phone.
Sir Chris, I would need your insight regarding this one. I may have skipped something important or maybe there might be a drawback for this.
Or, you may have other suggestions that is much better.
Thank you so much in advance.
