im running callmanager express 4.1 with sip trunk to ITSP.
now the provider complaint that i was calling out with numbers that where not mine, and that screw up his billing on me so hi threaten to shut my account down... I discovered that it did so when i call-forward to an external number like my cellphone, it uses the callers nr and make a call with that to my cell. I solved this by making a tranlation rule that makes all outgoing numbers transate to one of mine numbers.
and now i wonder if this can be made in a other better way, without the translation rule?
Grateful for any help!
Translation-rule is the proper way. And your ITSP should learn something from traditional telcos. If you call with the correct or wrong number, be sure you are billed anyway :)
