I’m trying to set up an Asterisk box (188.8.131.52 - old I know but I’m not the sysadmin so can’t change it) to accept calls from a SIP provider (VoipTalk in the UK, who generally are very good).
Their advice is to set up the incoming user as follows:
(note this works with their IAX connection… but I’m trying SIP for a change)
However, when I dial the number, the SIP debug output reveals it cannot find the user. Further investigation showed that if I configure the user like this:
Then it can find the user and everything ‘works’. I can’t believe for a minute that this is entirely correct. Unless I’m really not understanding something.
So, has anyone else come across a similar problem where the CID and SIP userID appear to be swapped?
I have a support ticket in with the supplier to see if they know what’s wrong, but I imagine it’s my Asterisk configuration somehow. I’ve spent an afternoon on this so far with no luck. It’s annoying!
