RE: [Iaxclient-devel] firewalls and TCP connections ... ?

[Chris G. N. <cg...@gl...>]

so, after a first pass on the sources, perhaps add a new interface/beef =
up lib/libiax2/src/iax.c to have:

int iax_init(int preferredportno, int ipflavor)  {

....

    netfd =3D socket(AF_INET, ip_flavor, IPPROTO_IP);

}


and the existing routine would become a wrapper...

int iax_init(int preferredportno) {=20
   return(iax_init(preferredportno, SOCK_DGRAM))=20
}

????

Unfortunately, our solution is not for sale, but you can probably find=20
other similar solutions with your friend google:

I think zebedee does this; it can even encrypt/compress things=20
[compression probably not too helpful].

Also This might work:
