Hi, i have installed 3 extensions to the following:
- Yealink T-31P (the extension assigned here is using pjsip protocol)
- Zoiper softphone
- 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.

Please advice, thank you.
