Although i feel it may not be related with asterisk but still posting for hope.
Problem is if i want to call to a pstn no from voip service or phone i dont see the caller id . I can see it if i call to another sip device or softphone.
My question is what configuration left to be done?
In sip.conf under user context there should be callerid=<> whatever number i give right? Well there must be some authentication when voip to pstn swicthing of this coming phone no it must be done by the provider who is switching this right?
Let explain the scenario details. i have my incoming did for my hard phone.
now in hard phone configuration caller id enable feature, send caller id,
name (which will show as caller id ) field is filled out i mean everything is done what need to be done. Now i route for my outgoing call by another provider who terminate it far end dont know how are they switching to pstn but they said they can. But still coimg as unknown number.
Can any one give any idea?
