Dear All My Asterisk has sip connection with an external sip server @192.168.0.139. I have sip inbound and outbound calls as ok . But there is a problem on sip incoming calls . To illustrate the problem , please suppose the sip phone on external sip server dials my Asterisk sip phone @6672019 . Please find below this sip phone profile inside my sip.conf : [6672019] type=friend ;type=peer ;type=user context=sip-outgoing UserName=6672019 secret=uT0Pc4rU callerid=6672019<6672019> mailbox=6672019 at default canreinvite=no host=dynamic nat=no When the sip phone on external sip server calls my sip @6672019 the sip incoming calls can gets through if and only if the external sip server sends the CallerId field in his SIP INVITE everything other than 667XXXX . For example , sending it like 021 667XXXX (with area code included) can gets through . Can you please let me know how can I overcome this as I need to show the correct CallerId on my sip phone ?
