I have a scenario where the PSTN to SIP gateway (AudioCodes) I am using sets the From header to 'anonymous' when it does not receive a Calling Name from the PSTN side.
The modified INVITE from the gateway then looks like this (changed some numbers and IP's): From: "anonymous" <sip:[email protected]>;tag=1c49690767. To: <sip:[email protected];user=phone>. CSeq: 1 INVITE. Contact: <sip:[email protected]>. When the gateway does receive the Calling Name from the PSTN, it looks like this: From: "HONOLULU HI" <sip:[email protected]>;tag=1c1248847826. To: <sip:[email protected];user=phone>. CSeq: 1 INVITE. Contact: <sip:[email protected]>. In the first instance, I want to re-write the From header because I do in fact have the calling number from the Contact header. In theory, the PSTN gateway should sort this out for me and not send me the 'anonymous' From header but I've searched the manuals and it doesn't. Anyone else encountered this? This is the IF statement that satisfies the criteria: if($fu=='sip:[email protected]' && $ct=~"^<sip:[2-9][0-9]{2}[2-9][0-9]{6}@") { xlog("L_INFO", "fix anonymous\n"); } The final From would be: From: $ct;$ft --> That is Contact header variable;From tag I had a look at the UAC module but using the function uac_replace_from(), I don't know how to strip the '<' and '>' of the Contact header to satisfy the arguments of the function. Is it possible? I'm thinking that using the UAC is preferable to what I'm proposing below. Does this method sound sane? Or is it dangerous?: remove_hf("From"); append_hf("From: $ct;$ft\r\n"); Thanks, Julian _______________________________________________ Users mailing list [email protected] http://lists.opensips.org/cgi-bin/mailman/listinfo/users
