Summary:                    RTP delayed by 30 seconds when SIP calls is bridged
via two LOCAL channel.
Description: 
My scenario is as follows:

1a. Call is originated via .call file on a 'Caller' LOCAL channel.
1b. 'Caller' LOCAL channel dials a SIP phone.

2a. When 'Caller' SIP phone answers, it is connected to 'Called' LOCAL
channel.
2b. 'Called' LOCAL channel dials another SIP phone.

Problem: RTP stream from 'Called' SIP phone is not relayed to the 'Caller'
for the first 30 seconds. 

This can be seen in 'full.log' (attached) line 1768 (when Called phone
answers) and line 1769 (30 seconds later - when audio is finally delivered
to the Caller).

How to reproduce:
1. Edit line 4 of extensions.conf (attached).
2. Copy test.call (attached) to /var/spool/asterisk/outgoing/
3. Answer 'Called' phone.
4. There will be silence for the first 30 seconds.

Please accept my apology.

This "bug" turned out to be miss configured firewall on my development
machine.

After correcting iptables rules everything works as expected. No delay in
RTP streams. 

Best regards,
