Jabber Client (Windows) can not start a video call to Jabber IOS

[Gura24]

Hello,

I can't start a video call to my mobile (Jabber IOS) device. (internal -> external) (external-internal is working fine)

Info: I have a SIP-Trunk from CUCM to ISP

As first I tried to disable the video function on my CSF device and finally I can start a audio call. But I also want to start a video call. How I can do this?

Thanks for help!

What video ports I have to open on the firewall? (Outbound -> DMZ)
I forgot to tell, Im calling via sip URI!

thanks!

Hello,

Sry I’m using both.

Jabber (Windows) -> Jabber IOS, internal to external. Is not working, but external to internal is fine. I already enabled the video function (setting->call options) in the client.

Just4info: im using an expressway

Cheers

Just curios, whats the behaviour when you connect the IOS device internally on your wifi. Is video working ?

Can you try enabling the MTP on the SIP trunk and see that makes a difference.

Also try a pcap Wireshark and observe. Basically the video/voice ports are the RTP ports 16384 to 32766

Hope this helps!

Cheers
Rath!

Enabled MTP on SIP Trunk fixed that issue! Thx!
