Dear,
Kindly guide with the 2 issues mentioned below
*#1* - *Host unreachable 0 last qualify 0 (only in 3G**)*
I am trying to use SIP client over 3G. It registers and call can be
initiated from the client but it can't receive call; cause *asterisk
sever *marks it as unreachable immediately after registration.
"[2014-10-08 14:32:47] NOTICE[1610]: chan_sip.c:29596 sip_poke_noanswer:
Peer '1007' is now UNREACHABLE! Last qualify: 0"
The above work well when I turn off 3g and switch over to my office
wifi. Kindly guide if there are specific settings for 3G / mobile network.
*#2* - *SIP retransmits - no reply to our critical packet*
Issue occurs when dialing a call out from a remote wifi network ( in my
case office wifi ), Its auto disconnected within 10s with SIP
Retransmissions notice / warning message
However if a call is initiated from home local network ( ipad ) to the
phone ( registered with asterisk over office wifi )... all works well !
*Issues with call sequence in a table form*
*Local Device* Asterisk SIP Server & Router with NAT Port Forwards
iPad with Bria SIP Client
*Remote Device* iPhone with Bria SIP Client
*CALL SEQUENCE*
*Remote Network* *From * *To* *Works/Failed* *Issue*
*3G* Ipad ( local ) Iphone ( remote ) FAILED Host unreachable 0 last
qualify 0 !
Iphone ( remote ) Ipad ( local via NAT ) WORKS -- both Audio &
Video
*Office Wifi / Broadband* Ipad ( local ) Iphone ( remote ) WORKS --
both Audio & Video
Iphone ( remote ) Ipad ( local via NAT ) FAILED SIP retransmits - no

Kindly guide
