Hello All,

Got one customer and he is getting disconnection within 15 seconds when
he tries to make outbound calls. Initially, it was working fine without
any glitches... Other customers on the same system are working fine, its
just with this customer only.

This is the error message thrown by Asterisk on the CLI: -

Jan 18 12:23:30 WARNING[30532]: chan_sip.c:1228 retrans_pkt: Maximum
retries exceeded on transmission 20e5feaa-1d3d7ef1 at 192.168.1.2 for seqno
102 (Critical Response)
Jan 18 12:23:30 WARNING[30532]: chan_sip.c:1245 retrans_pkt: Hanging up
call 20e5feaa-1d3d7ef1 at 192.168.1.2 - no reply to our critical packet.

Customer can receive inbound calls without any disconnections, its just
when he tries to make outbound calls.

All outbound calls are sent to Nextone SoftSwitch and default codec is
G729a. Customer has Linksys SPA-2102 - firmware ver 3.3.6 and Asterisk
version 1.2.18.

Thanking in advance...

Cheers,
Nitesh
