SIP transfer to mobile

[szpuni]

Hi Lads.

I have a problem with the SIP on IPO 500.
I have set up a transfer to mobile on night mode instead of getting a voice mail.

The call is comming through but when I answer a call on my mobile there is no voice.

UDP xx.xx.1.228:5060 -> xxx.xxx.104.45:5060
INVITE sip:landline@xx.xx.81.188 SIP/2.0

Look like you have a routing problem.
Check the SIP line, only the "registratio required" an "In service" nee to be ticked.
Check the LAN1/2 the firewall profile needs to be <NONE>

All what you asking is setted in propertly, when the call forward is off call is comming through and there is a voice.
This is not working only on the call forward, but if I transfer the call on to the mobile everything is working.

 

[Bas1234]

Are you using IPDect or twinned IPPhones?
What version are you using?

I`m using digitals and ip phones,5410 and 5402SWIP
Firmware is 4,2

 

[Bas1234]

Are u using Cisco a router?

IF so check this in your router.

ip nat service sip udp 5060
(Reservates this port for SIP standard)



ip nat inside source static udp xxx.xxx.1.250 5060 interface Dialer1 5060
(Forward port 5060 UDP to IPO)

szpuni,

What kind of firewall are you using?

We've been haunted with this problem since we went to SIP, back with firmware 4.0 (we are now at 4.2 with the same problem). We've found some work-arounds though...

Here's what we've found (each of the below work, independent of each other):

1. If you enable "binding refresh" on the Network Topology and set it to 30 seconds, or less, audio works.

2. If you route the "second leg" of the outbound call using a different SIP provider, audio works (we have three SIP providers).

3. If you do not go thorugh a firewall, and just put the IPO on a public IP (use lan2 if you want, and send your SIP in/out through that), audio works.

Now it`s sorted.
There was some problem with the firewall, as soon as I stick it on to the public address everything starts working.

Thanks Lads

hi szpuni.

i wouldn't recommend ever putting your public ips on a web forum. you don't know who is watching.
