[OpenSIPS-Users] Users Digest, Vol 164, Issue 6

Wed Mar 9 19:08:33 UTC 2022

My guess is the lack of quoting is due to the SIP stack and not anything you are doing with your commands. The Name portion of a Name-Addr spec is only required to be quoted if certain special characters (most notably spaces) are present. Otherwise the quotes are not required. I’m guessing OpenSIPS’ SIP stack is just being efficient and only adding quotes when required. I’m not sure if that is configurable, but I’m not aware of any setting for it.

My guess is that if you were to try this:

$avp(ds)="a b c";
uac_replace_from($avp(ds),"");

You would find that the resulting output name would have quotes as required.

However, it should not matter as if quotes are not required then the receiving SIP agent should be fine with them not being present. May I ask why it is important to you that the quotes be present? Is it causing an issue with some non-compliant device?

AVP is for sure supported on 3.1.x and up.  We use the following:

uac_replace_from($avp(caller_cnam),"”);
