Hello.

I have the following in sip.conf

[sip09]

type=peer

defaultuser=sip09

nat=yes

qualify=no

secret=sip09

host=dynamic

context=outgoing

dtmfmode=rfc2833

disallow=all

allow=ulaw

allow=alaw

allow=h263p

deny=0.0.0.0/0.0.0.0

permit2.168.2.2/255.255.255.255

jbenable = yes

jbforce = yes

jbmaxsize = 100

jbresyncthreshold = 200

jbimpl = fixed

transport=tcp

sendrpid=yes

And these settings in Android native client.

Username: sip09

Password: sip09

Server: 192.168.1.10

Username at authentication: sip09

Display name: Same as username

Outgoing proxy: 192.168.1.10

Port: 5060

Transport: TCP

Send keep alive: Always

However, if I make a call FROM android phone, call is dropped after 30
seconds, regardless of answer or not. If I make call TO android phone, it works normally.

No NAT problems inbetween, there is a VPN between the phone and SIP server with full access.

I guess I need to do some trick to have it work with Android. Apparently the packets are received in both ends – else audio wouldn’t work, but guess the stock native SIP client on android ignores certain packets right?

This is an Android 9 phone.

Additionally, I wonder if its possible to change the callerid shown in display when calling out? Like RPID. It works on my desktop phones, if I
enter a short code, the full name and number is shown on display, but on the Android phone, it doesn’t work, only the dialled shortnumber is shown.

Also I wonder if its possible to have asterisk send the remote callerid
(when receiving a call) in such a way it gets stored in call log with full names and such – without having to resort to using phonebook.
