More info. Turns out that the 5mins or so is spent on the function rc = getaddrinfo(nodecopy, NULL, &hint, &res); which is in pj_getaddrinfo() in Addr_resolv_sock.c Any idea why this function take a long time on the iphone to execute when there is no internet connectivity on the local WiFi?

But it turns out that we do get a REGISTER sent eventually it takes 5 minutes for that to happen. Then after 5 minutes everything is all good and Siphon/PJSIP works as expected after that and you can receive and make calls. > > Anyone know what the problem might be? > > > On 24/03/2010, at 8:13 PM, Joseph Rukshan Fonseka wrote: > >> Hi All, >> >> I have been debugging Siphon and why it does not connect to the SIP client. >> The scenario is a PABX running on my laptop, and my laptop and iPhone are connected via a local WiFI. >> There is no internet connectivity on this WiFi (that is the key difference in which PJSIP fails to connect, if there was internet connectivity in the WiFi all is ok). >> >> I have debugged and in Siphon there is absolutely no difference between a WiFI that has internet connectivity or not. >> The same lines of code are executed.
