Extension to Extension Call Doesn't Work

Hi, i have installed 3 extensions to the following:

1. Yealink T-31P (the extension assigned here is using pjsip protocol)
2. Zoiper softphone
3. MicroSIP Softphone (the extension assigned here is using pjsip protocol)

All extensions are successfully registered, however extension calls are not working with this error:

Call to Phone (103), rejected.
1:54 PM
Decline (code: 603)

Please advice, thank you.
