[SIPForum-discussion] Dummy Telephone Number in PSTN out

[Mario]

Hi Members,

1. What is P-Asserted-ID SIP header used for?

2. If you would like to re-write the telephone number coming in from:
field, by a dummy telephone number
which SIP field might be used to store this dummy number to be
exchange in a further step (in the from: field)?

....(I really do not see the reason behind this wish, any idea will be welcome)

Thanks a lot in advanced for your contributions,
kind Regards,
/Mario
