1. I see a high packet loss. almost 86%. you could hardly hear anything with that much packet loss. as out of ever 10 pckets 8.6 packt are droppd. 

2. Try changing the network from 3g/4g to wifi or fiber because some isp block 5060. like (saudi Arabia)

use VPN and thn login jabber using MRA.

Hi Ammar,

I just checked with WiFi and it's working fine for me.

Means, UAE also block 5060 now :-(

Please advise what is the workaround now to fix it over ISP mobile data?

Thank you a lot.

In Gulf they have blocked Skype, Line, imo and many other apps.

only work around is to use Internet with VPN n then use jabber from internet.

Hi ammar,

This is really disappointing by gulf as we have enterprise solution... 

If we change ports from 5060/5061 to unknown ports then it will work?

what do you think?

[Ammar Saood]

depends on what kind of inspection the ISP is doing. mostly they have very sophisticated firewalls. 

if its 5060/5061 ports only then it will work if u change the port. 

if its  RTP packet inspection then changing the port might not give desired result.

still u can try and keep us posted.
