Unable to make a call from LTE

Open mattyleggy opened this issue 6 years ago • 8 comments

When trying to make a call on LTE, it just stays on the "ringing" screen but never actually dials. Works fine on WiFi. The calling state shows as PJSIP_INV_STATE_CALLING.

Receiving calls on LTE work just fine. Anyone else have this problem? The outbound LTE calls work fine on other apps like CSipSimple and Zoiper without any NAT settings enabled like STUN or ICE.

It works for some LTE networks but not for others. I haven't spent much time into finding a solution as of yet.

Are you getting this on iOS or Android? I'm running into an issue that I can't even register with the SIP server (it returns a bad gateway error) with an iPhone on T-Mobile LTE. Could it be related to iOS 9+ only allowing IPv6 on cellular networks? See https://arstechnica.com/gadgets/2015/06/apple-to-ios-devs-ipv6-only-cell-service-is-coming-soon-get-your-apps-ready/

I met the same problem, and I had resolved it by removing some supporting codec to decrease the UDP packet size;

How did you do that, can you send me the list codec you remain?

I just removed some codec which is not supported by my server, and I canot find the list now for some reason.
