Re: Problem with call transfer (CME)

mcastillocandia · ‎09-04-2018

Hello

I am currently setting up a CME with a SIP Tunk for calls to a remote destination (external numbers).

Calls between CME and external numbers work OK, but if I attempt to put a call on hold or to transfer it, that call ends abruptly.

In a CM scenario, I would force the SIP Trunk to use MTP, but in CME I don't find a way to force SIP Phones to use MTP (there is a mtp command for ephones though).

Is it possible to force mtp on a SIP Phone in CME?

Is there any other possible cause for the failure of Call on Hold and Call Transfer?

I would appreciate any help with this.

What codec is negotiated for the call ? What codecs does your ITSP support ? What codec is your MOH file ?
For transfer and forwards, ensure the REFER and 302 is disabled. They are enabled by default on IOS. ITSP's don't want a SIP REFER or 302 and would drop the calls.

voice service voip
sip
no supplementary-service sip-refer
no supplementary-service moved-temp

Just check the commands. There might be a syntax error. :P

Hello
thank you very much for your help

the trace of the call indicates codec negotiation g279

What codec is negotiated for the call ?

g729

What codecs does your ITSP support ?

g729

What codec is your MOH file ?

Enable the following for me -

debug ccsip message
debug ccsip error
debug voice ccapi inout

Make a test call, collect them in a text file and attach.

Can you share ANI, DNIS and RDNIS info please ?

tfsnchez88 · ‎01-03-2019

I have the same problem, so could you solve this issue?

ashok_boin · ‎01-03-2019

Hi,

Have you tried contacting ITSP (your provider) about this error? Generally, ITSP expects "Early offer (SDP in in initial invite) but in your case SDP is also there in your 1st Invite.

Regards...

Ashok.

With best regards...

Codec should not be a problem because the ITSP accepted the initial INVITE with g729.

The ITSP may be disconnecting the call because of the a=sendonly attribute in the INVITE sent to them when pressing Transfer.

Try adding this command on the router.

voice service voip

sip

midcall-signaling block

This will block the INVITE for sendonly being sent to the ITSP. The ITSP leg will always remain connected and not change states.

I have the same problem, I issue this command but not work. So my problem its intermittent, before two or tree calls, the next one it drop.
