Anybody ever try use this feature for SIP trunks? If so, what needs to be done to impliment? Have a customer with thousands of IP sets and am running into issues with calls getting rejected due to the outbound caller id not registered with the Sip Trunk provider.
It depends if you provider accepts it.
I think i've got a doc about it somewhere.
What system and version are we talking about?
Thanks, got it working. Very simple. Provider was making it sound complex.
I'm also having an issue with P asserted. Sip provider says it not being sent and I'm having problems with the presented cli's on outband calls. I've swapped from peering to sip carrier reg because I saw the option for p asserted in sip carrier options and turn it to primary (and alternate) but still no apparently!! would be really grateful of some help.
sorry should this have been a new thread?
I have started a new thread for this
