Hello,
Can anyone please help me on this? I try to register a SIP phone with full E164 format to CME but not succeed. Just a sample, I create a voice register dn with number +1647200xxxx, phone is failed to register. If I change number to 1647200xxxx or just xxxx, phone is registered successfully. There is no issue if I use a SCCP phone.
Thanks in advance,
Duy
