Dear Asterisk Team

I Hope every thing is fine with you. 
I was using Asterisk 1.8.22.0 and configured more than 100 extensions and 4 to 5 SIP trunks some years ago. Suddenly I planned to upgrade my asterisk box. I configured the new asterisk server with Asterisk 16.29.0. every thing is working fine but my one sip trunk is registered but when incoming or outgoing calls land on this server both receiver and caller can not hear the voice of each other. 
I investigate the RTP Packet and found that my asterisk server user new SSRC after 200 OK. 
Below are the configuration details. 
[general]
context = default  
allowguest = yes
allowoverlap = yes 
bindport=5060
udpbindaddr = 0.0.0.0
tcpenable = no  
tcpbindaddr = 0.0.0.0
transport = udp  
srvlookup = yes  
videosupport = yes
localnet=10.5.0.0/255.255.0.0
externip = 0.0.0.0
qualify=yes
nat=yes	
subscribecontext = default

 [PTCL]
fromuser = XXXXXXXXXXX
authname = XXXXXXXXXXX
host = XX.XX.XX.XX
type = peer
nat = comedia
dtmfmode=inband
allow = ulaw
allow = alaw
qualify = yes
directmedia=no
context = UAN-Calling

Kindly help me for the same and Thanks in advance.
